Option to prevent scrolling up after preview refresh

[allefeld]

Description

This is related to #3648, but not exactly the same. There @fecet requested synchronization between the position in the editor position and the position in the HTML preview, which would of course be at least partially editor-specific and therefore not (exclusively) a quarto-cli issue.

For me it would be sufficient to have an option which prevents each refresh of quarto preview from scrolling to the top of the document. That behavior is really inconvenient, in particular when editing complex input where keeping an eye on the preview is helpful, and when the edited part is further down in a long document.

I did some digging, and found that quarto preview has an option --no-navigate which seems to do this, and it works with the preview in an external browser if I start quarto preview manually. However, there seems to be no way to request issuing this option to quarto preview when started from an editor or IDE.

I propose to add a YAML option navigate with boolean value (e.g. under the editor key) where navigate: false has the same effect as the --no-navigate option.

this would be useful!

For me, --navigate is working with Chromium, but not with Firefox. Also works with VSCode built-in browser. Already a great help, though.

In the meantime I realised that this functionality already exists at least for the VS Code built-in preview; I think this post was prompted by that feature failing with a specific old Quarto version. I'm not closing it because the original post has a few upvotes, and while I'm happy now maybe there is actually something to be improved.
