Description Eyal Rozenberg 2022-09-14 09:59:33 UTC 
(This is the Impress equivalent of bug 32531)

When moving in the same direction across text in an LTR table, and passing via a single RTL column, the cursor will only pass one position in the RTL column - to the left of all of the text - and proceed to move to the next LTR column.

To reproduce:

1. Create a new impress presentation.
2. Be in an LTR slide.
3. Add a table with at least 3 columns (double-check they are LTR).
4. Choose a row and add some text to each column of that row (e.g. "hello").
5. Make the second leftmost colum RTL, e.g. by selecting the whole column and pressing the RTL paragraph button on the toolbar.
6. Place the cursor at the leftmost point in the leftmost column, in your chosen row with the text.
7. Repeatedly move the cursor to the right using the right arrow key.
8. Note the sequence of cursor positions.

Expected: The cursor traverses all points between characters in each of the columns as well as the left and right sides of the text in each column.


Actual: The cursor reaches the left side position in the RTL column as expected, then continues to the left side position on the next LTR column to its right. The rest of the traversal is as expected.

This presentation has a table with one RTL column, and text in every column. Move the cursor from the leftmost character rightwards to experience the bug.

I reproduce. I don't know about the meta bug, because this can be reproduced in a non-RTL UI (not having to use SAL_RTL_ENABLED=1).

Seen in 3.5 as well, so probably inherited.

Ok, switching to the more general meta-bug.
