Steps to reproduce:
1. Insert a picture.
2. Attempt to drag/stretch it outside the page boundary.
The image stops at the page boundary.
The image drags to anywhere on the plane.

Effect is reproducible with "LibreOffice 18.104.22.168 (RC1) German UI/Locale [Build-ID: 7306755-f4f605c-738527d-1cf4bc1-9930dc8] on German WIN7 Home Premium (64bit). But is that really bug? It never worked different in LibO / OOo. But for some resizing and similar it might be useful to have that possibility.
That's all the same for objects like DRAW shapes, Spreadsheet tables
But I indeed see a strange effect: When I drag the picture around on the page, only a border frame follows the mouse pointer. At top, right, bottom border that frame can not exceed the page margins, only the left page border will be exceeded (this not with Math formulas). But the frame jumps back when I release the mouse button, and the picture will not exceed the page border. That is a little worrying, but has nothing to do with original report.
In LibreOffice 22.214.171.124 can be reproduce with workaround:
1. Insert a picture
2. Crop the picture
3. Drag to page boundary
But the complete image can't be dragged outside the page boundary.
Confirmed in 126.96.36.199.
There is no problem in doing the same in Draw.
Also if the image is a polygon with a very wide stroke, half of the stroke can be outside the page.
The cropping workaround for polygons requires you to copy the polygon to Draw, then Figure > Subtract with a rectangle, and then copying back.
This is extremely cumbersome compared to Microsoft Word where you simply drag the image outside the page.

This is a major interoperability issue as other word processors support this (e.g. Microsoft Word, Google Docs, Calligra Words).

Partial workaround: If you do multi-page view, then you can actually move object down-right partially off the page - as long as there are pages in that area.
This tells me that there is no problem in the file format to save the coordinates.
Still reproducible in
