Steps to reproduce:
- In the wikitext editor, create a table with three rows and two columns
- Add a rowspan=2 on the second column, spanning rows 2 and 3
- Add content to all cells
- In the visual editor, move the first row "below" twice, so as to move it to the bottom of the table
Actual result: The content that was originally in (1, 2) was lost while passing through the rowspan.
Expected result: I'm not sure. Maybe the current result is the expected behavior, and maybe this will be moot once T125145 is solved. I thought I'd open this just to make sure you were aware of it.
