Synchronized scrolling in live preview is offset after edit in case LaTeX formulas are present

[Arnache]

My config

Ubuntu 24.04LTS ReText 8.02 Installed MathJax locally with sudo apt install libjs-mathjax

Issue, with steps to reproduce

Enable WebEngine (Chromium) Type a somewhat long text with math in it. Now move back to the middle of the edited text and type one character: then the preview auto-updates, but the scrolling is wrong (what you typed is off-screen).

Possible cause

I suspect the scrolling is computed before the math is rendered, because the preview shows TeX being gradually converted.

Workaround

You recover the right scrolling by pressing any arrow key.
