Since the sidebar will be the only location for the styles and formatting dialog in 4.4.x+, I'm looking for a way to make it behave in a sane, consistent manner, hopefully similar to the old dialog. This should be easy enough using an undocked sidebar. The undocked sidebar pops up in a number of different positions depending on how you summon it.
I think the ideal behavior would be to have the undocked sidebar remember its last location and always be summoned there. The previous styles and formatting dialog didn't remember it's last location, but would always open positioned relative to the right center of the main LibreOffice window.
Currently, the sidebar does remember its position when switching between docked/undocked mode.
But once undocked mode is enabled, dismissing and reenabling the sidebar opens it positioned at pixel 0,0 (top left) of LO's main window. This is not ideal, since we would expect the sidebar to appear at the right side of LibreOffice.
Steps to reproduce
1. Open Writer
2. If testing using 4.3, enable sidebar. If testing using 4.4, the sidebar will already be enabled by default.
3. Click sidebar menu button -> Undock
4. Note that by default, the undocked sidebar appears with its origin at the far left of the screen, but positioned vertically based on the top of LibreOffice's window.
5. Reposition the window on the right side of LO, where you'd expect it.
6. Dismiss the sidebar using View -> Sidebar (note that you can't close the sidebar using the "X" in its window decorations because of bug 87217)
7. Reenable the sidebar using View -> Sidebar
The sidebar should reappear where we last positioned it on the right side of the LibreOffice window.
The sidebar shows up positioned in the extreme top left of the main LibreOffice window.
While it would be nice if LibreOffice remembered the position, I would be happy enough if it behaved like the current Styles dialog. The Styles dialog always appears relative to the right center of the main LibreOffice window.
I tested this using LibreOffice 184.108.40.206 rc1 under 32bit Fedora 17. I might be willing to blame some of the positioning on the window manager, but LibreOffice currently handles this properly with the Styles dialog.
Also, the initial undocked view is completely useless, since it is only wide enough for the category icons, but I'll report that as another bug if I can't find an existing one.
LibreOffice 4.4 beta 2
I can't confirm the issue. For me the position is kept after I disable and then reenable the sidebar.

Screenshot of tiny undocked sidebar
I just tested under another environment: Fedora 20 using KDE, using a nightly of 220.127.116.11 from 2014-12-23. As you can see in the attached screenshot, the undocked sidebar window pops up on the far left side and is unusably narrow.
Interestingly, the undocked sidebar window disappears when libreoffice loses focus. It does reappear when LibreOffice regains focus. Most definitely unrelated, but it's odd.
I was a bit hasty in my last response and mixed up my bugs. :) I was thinking of the somewhat related bug 88182.
I've just installed LibreOffice 18.104.22.168 rc1 under an up-to-date Archbang install (openbox wm) and can't reproduce this bug. I then tested the same version of LO under Mint 17 using XFCE and couldn't reproduce it. LibreOffice (or possibly the WM) does appear to remember the undocked sidebar's last position.
I originally tested this using IceWM using Fedora 17, but that setup has a number of complicating attributes. I should have tested this under different environments.
I still want to look into this a bit more tomorrow, but I'm going to mark this as "Resolved: Invalid" until I can prove otherwise.
No worries. Happy to have you on board testing the hell out of LibreOffice and offering suggestions for improvement :)
