Issue with text replacement on mac

[twine-and-hope]

Steps to reproduce

The error involves the text replacement feature built into MacOS (I'm running Ventura 13.2); you need to have a text replacement rule set up before you can replicate the error.

To add a new text replacement rule:

1. open settings and go to 'Keyboard'
2. select 'Text Replacements...'
3. press the '+' in the bottom left corner of the dialog that appears
4. enter your replacement rules and click 'Add'

Screenshots:

To replicate the error:

1. Open element
2. Type your term to be replaced into the text box

Outcome

What did you expect?

Here is a video of the expected behaviour in a unrelated text editor, followed by the error behaviour in Element.

1. The text replacement rules automatically trigger when you press the space bar after enter a term from the list of 'Replace' terms

2. It removes the 'Replace' term (from the replacement rule) and inserts the 'With' term (from the replacement rule), followed by a space.

In other programs:
3a. After the replacement, the cursor ends up at the end of the new text, after the space

What happened instead?

In Element:
3b. After the replacement, the cursor ends up adjacent to the inserted 'With' term, before the space

This error is new as of a recent Element update. Prior to November 2025, text replacement worked as expected in Element.

Cannot reproduce on web or desktop. Can reproduce a different issue with the Labs Rich Text Editor enabled which you do not appear to have enabled.
