Description:
Description:
The undo button creates a page break out of nothing, if the table is on the first line of the second page, and the last action was the removal of the first line above the table.

Steps to Reproduce:
1. Create a new Text Document
2. Insert a man. page break (Ctrl+Return)
(There should now be 2 cols)
3. Hit Ctrl+F12 and Return to insert an empty two by two table
4. Return to move the table one line down
5. Del to remove the line above the table
6. Ctrl+Z to undo the last action

Actual Results:
A second man. page break appears and the table goes to the third page.

Expected Results:
The Table should move one line down, like i insert an paragraph per return key.


Reproducible: Always


User Profile Reset: No

Additional Info:
Steps 4-6 can be repeated as often as desired, which leads to new page breaks being inserted correspondingly often.

I made a mistake in the description of the necessary steps. The information "(There should now be 2 cols)" under point three is incorrect. However, the actions that need to be performed are unchanged.

Steps to Reproduce:
1. Create a new Text Document
2. Insert a man. page break (Ctrl+Return)
3. Hit Ctrl+F12 and Return to insert an empty two by two table
4. Return to move the table one line down
5. Del to remove the line above the table
6. Ctrl+Z to undo the last action
