Description

In the Add screen, changing the alignment of text with a MathJax block directly on the line below it causes the MathJax block to be deleted.

Produced on https://github.com/ankitects/anki/releases/tag/26.05 on Pop!_OS 24.04 LTS

To recreate, suppose:

Move text cursor to within the top line of text, then click to change text alignment (in this case to centred, but this happens regardless of which alignment):

Result - MathJax block deleted:

I'm happy to work on this as a first issue if accepted!

Contributor guide

Research direction
Examine the text alignment implementation in the editor. Trace what happens when the user changes alignment while a MathJax block is on the adjacent line. Identify where the MathJax block is removed and ensure the operation preserves it.
