Intermittent page navigation issues

[lkirkwood]

Hey, first of all absolutely loving this project, thanks for creating it!

When using the vim-style navigation keys to scroll the page, I find it often gets stuck especially when viewing PDFs. To reproduce, simply open a PDF and then try to navigate using j/k. If you scroll the page a little with the mouse, you can navigate using j/k afterwards, but if you stop for say 10 seconds the keys become unresponsive again.

A separate but related issue is scrolling something like gmail with an inner window that scrolls and an outer window that doesn't.

Super happy to contribute a fix if anyone would know where to start on this. Apologies if this is something people have already found.

Thanks for the report, I have experienced this as well.

If you're still interested in contributing, something that would be very helpful is researching how existing extensions have implemented scrolling, in case they ran into similar issues.

The current implementation uses a mix of internal Firefox APIs and standard DOM APIs because I ran into these inconsistency issues using both versions. So it's a terrible amalgamation of both, see the comment in this function:

glide/src/glide/browser/base/content/utils/dom.mts

Line 215 in 9cb7628

export async function scroll(

This is also why nested scrolling doesn't work right now.
