Scroll View URL Hash Not Working #3815
Description
Thank you for this library!
We've recently tried implementing the scroll view ability but are noticing an issue with the slide hash logic. Everything works as expected for the default horizontal navigation behaviour, but on scroll view it seems like any slides past the halfway point of the total slides seems to get offset by 1 index.
For example, here's with the default horizontal view, refreshing the page when the slide hash is present loads the correct slide as expected:
horizontal.mov
However, with scroll view enabled, when you have a slide more than halfway through the presentation in the hash, it's off by one index and loads the previous slide:
vertical.mov
Here's another example showing it happens on a presentation with less slides as well:
less_slides.mov
This is also an issue when using the slide API method. I tried debugging the reveal.js code and can't seem to find where this is happening - the variables seem like it has the correct slide but the index is getting altered somewhere along the way that I haven't tracked down. I also tried running a sync before calling slide but that also didn't seem to help.
Is there a way to get around this issue to make sure it uses the correct slide when hashes are used with scroll view? Thank you!

fix(slides): disable scroll view on mobile to prevent crash (#10212)

We experienced similar behavior.
We don't need scroll view, so we disabled it in our project via
scrollActivationWidth: 0. Not an answer to your question, and certainly not a real fix - but scroll view (in my opinion) isn't a very useful feature anyway, so for people stopping by because of a web search, this might be a useful hint.fix(slides): disable scroll view on mobile to prevent crash (marimo-t…
scroll mode: fix navigation landing on the previous slide

That should fix it and it doesn't change the default.
The other patches changes the default and doesn't fix it.
Note: I pesonally think the default should change, but it should still be fixed.
