Short description of error
A strip does not snap to itself, but Hold Offset is something whose position may remain unchanged in some cases:
{F10243791,size=full}

Proposal
The idea is to track those cases where the Hold Offset of transformed strips doesn't change and allow snapping for them.

Actually, it doesn't snap to Hold points at all.

I'm still not sure what this "Hold Offset" is.
The manual didn't help much either.
@iss, can you shed some light into this?

When you add a movie strip, the duration can be extended ex. after the last frame, producing freeze frames. Same thing with a hold split. The hold offset values can be changed in the sidebar time panel.

It's when you drag handle beyond strip content so it outputs static image. Kinda sorta, but in context of snapping that boundary is the hold offset.

Now strip does not snap to itself, so this is not a bug technically, but I can probably implement it.

In this case I edited the description and made the report a To Do.
It can still be closed or made a Known Issue if the implementation is problematic.

The main problem of having no snap point at the end of the source material is that users will end up with freeze frames in their edit, because the handle is covering the strip ends and you have to be zoomed in by a lot to actually see if there is an extra (freeze) frame or not. If snapping is not working at the hold points, a bracket design of the handles could be used instead(which also solves not being able to see the exact split points of ex. a waveform curve): D10297, but when zoomed out (1px > 1 frame) this still do not ensure the failure of adding unintentional freeze frames in strip ends or if hold splits are used.

The strange thing is that snapping at hold points was actually working at some point during the implementation of snapping: https://developer.blender.org/D11646#299437

Currently strips don't snap to themself, because this is bit more tricky to handle when more strips are selected.

So to resolve this consistently I would have to create special point pairs that would snap with each other, but not with any different points. Not impossible by any means though.

Actually snapping other strips to hold points properly isn't that useful, it is mainly for snapping to it self, as you call it, which is useful.

As I do not have anymore time or motivation for a continued investment in the Blender project, I'm giving up on this report for now.

Sorry to hear (thx again reporting). In my opinion we should not sweep this under the carpet (esp. since this already been confirmed), there is still a chance to get this fixed in the future and others might be affected by this issue as well.
Feel free to unsubscribe though.
