Sample DOCX file

Open the attached DOCX file in MS Word. It has a table with some equations in it. In the first column the equations are rotated because the text orientation is vertical.

However, when this file is opened in LO Writer, the equation gets misplaced and becomes invisible (see ODG file with screenshots detailing the bug). Resizing the column  has no effect on the formula visibility.

It seems the formula object is not being rotated either, because copying it and pasting it somewhere else in the text results in a horizontally-oriented object.

This ODG file compares how the file is rendered in Word and in Writer.

Comment 3 Aron Budea 2023-03-20 04:38:57 UTC
This was never really okay, because the formula was horizontal and not rotated even when it was shown (or even worse in older versions).

Nevertheless, it disappeared with the following commit:
