Description Stéphane Guillou (stragu) 2023-12-08 07:58:23 UTC 
If the anchoring of a form control that was resized to fit the cell is set "to cell" from the Control Properties dialog, it moves to another cell toward the top left.

Steps:
1. Open Calc (or open attachment and jump to step 6)
2. Insert > Form Control > Text box
3. Trace the control further than column C and row 2 (for example, on cell E10)
4. right-click on the control > Anchor > To cell (or "resize with cell", same thing)
5. right-click on the control > Fit to cell size
6. right-click on the control > Control properties > Anchor > To cell (repeatedly)

Result: the control jumps from cell to cell at each click, until it settles in cell C2. The change can't be undone.
Same happens with other controls, e.g. a Numerical Field.

Note that the setting does not have the option "To cell (resize with cell)", which might be related to the issue?

Also reproduced with sample file in Ooo 3.3, so issue is inherited (although the option to "Fit to Cell Size" was only added in 6.1 for bug 116108).

Seems to have to do with the position of the top-right corner, possibly because of rounding.

Samuel, I thought you might be interested?
