Option to temporarily disable slide sync in RevealJS preview

[fretwurst]

I frequently use Quarto with RevealJS to build presentation slides in Positron.
One issue I keep running into is the automatic slide synchronization during preview rendering:
After each quarto preview or render action, the Viewer pane jumps to the slide that presumably matches the current cursor position in the source.

Unfortunately, this matching is often inaccurate, especially in more complex decks. It jumps too far ahead or behind, and rarely hits the exact slide I’m working on.

This behavior makes it hard to fine-tune layouts or test for instance svg-animations because the preview keeps jumping away from the slide I'm currently working on.

Request: Please provide an option to temporarily disable this automatic synchronization:

Ideally as toggleable via command palette, so we can bind it to a keyboard shortcut.

That way, users could work on a specific slide without interruptions, and re-enable sync when they actually want to jump to a different position.

Thanks for considering this. I think it would be an improvement for anyone working with detailed RevealJS presentations.

Thank you so much for this report! This behavior is controlled by the Quarto VS Code extension, and they have had some discussions on problems in this area, such as quarto-dev/quarto-cli#1939 (see especially quarto-dev/quarto-cli#1939 (comment)).

Can you open an issue describing your problem (the preview sync doesn't work great all the time) and your suggested solution (user setting to disable the preview sync) for the Quarto extension repo at https://github.com/quarto-dev/quarto-cli/issues?

Thank you very much for the hint. I’ve transfered the discussion to quarto-dev/quarto-cli#12588.
