            Bug ID: 118559
           Summary: Calc: Bug with copy+paste for joined cells that also
                    breaks Undo/Redo
           Product: LibreOffice
           Version: 5.3.7.2 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: marcus at sternenschwarm.de

Description:
Consider this .ods (Calc) file:
C:\fakepath\problem_1.ods
When trying to copy and paste the green cell into the cells below, the
neighboring cells get damaged. When trying to Undo, the previous state of the
document isn't restored - thus Undo fails.
Could this bug please be fixed? My only workaround currently is to copy and
paste only one cell at a time which is quite annoying.
Here is a series of screenshot images that illustrates the problem:
(See screenshot images)

Steps to Reproduce:
1. Open the attached file problem_1.ods
2. Try to copy and paste the green cell into the cells below
3. Examine the damage
4. Try to Undo
5. Examine the damage

Workaround: Copy one cell at a time does not destroy the other cells.
Workaround is very cumbersome and not a practical solution.
Undo not working is especially concerning...

Actual Results:
a) Combined cells get destroyed.

b) An Undo does not repair the cells (by returning to the previous state).

Expected Results:
a) Combined cells stay the way they are.

b) An Undo does at least restore the previous state.


Reproducible: Always


User Profile Reset: No



Additional Info:
a) The thing that every normal user would expect.

b) The thing that every normal user would expect.

NOTE:
I have a series of screenshots that illustrates the problem.
I have a Calc file problem_1.ods that contains the problem.
