Description:
LO 6.3.1.2 bug

iMac (21.5-inch, Late 2013)
MacOS 10.14.6

Trying to make scorecards for my EFL classes here at a Japanese university. 

Text document: A4-size, Margins .59" all around
Content: Two multi-line tables each inside its own box shape (see attachment)

Bug: I attempted to simply make one table that takes up 45% of the top of the page, then copy, paste and align the new pasted copy below the original. I selected both boxed tables, went to the Format >> Align drop-down menu. I selected Right, hoping that the 2 boxed table would align their right edges. Instead one of the text content of one of the tables shifted to right-justified. OK, I made a mistake. As a Mac user I naturally, automatically clicked ⌘Z (Undo). Doing that completely changed the the formatting of the boxed table. I clicked ⌘Z again and LO again produced an unwanted format change in that table. I clicked ⌘Z again and the outcome was another perversion of the formatting. All the while the other boxed table remain unaffected.

This is unacceptable. LibreOffice docs should appropriately respond to the Mac's basic global commands of ⌘Z (Undo), etc. I have had this same bug in previous versions of LO.

Steps to Reproduce:
1.Make mistake in a table, & click ⌘Z;
2.Doing that completely changed the the formatting of the boxed table;
3.Click ⌘Z again, & table formatting queers even worse.

Actual Results:
Clicking ⌘Z again and LO again produced an unwanted format change in that table. I had to fix it manually.

Expected Results:
LO obeys global MacOS Redo key combo to undo the previous LO action.


Reproducible: Always


User Profile Reset: No
