Description

Wondering if it would be possible to make it less visually disruptive though, like maybe just greying out the drag symbol rather than having the whole element disappear and have everything jump around?

This PR makes grab bar remain visible but disabled (this is about grid mode only, list mode unchanged)

Two things i noticed.

The first one is that the user can drag the grab bar when its disabled. Im not sure if we need todo anything about this though.

Second, grab bar shouldnt be available when there is only one video in playlist

Fixed grab bar draggable when disabled (unnecessary change from me)
However for grab bar it seems more consistent to show grab bar on custom sort regardless of no. of videos (just like when videos being deleted

I've tested the MR with different scenarios and it works fine

I would tend to say that disabling the grab bar would have made sense if the drop-down sort menu was always displayed. It would have indicated that, indeed it's a custom sort, but you can't sort one video.
With the "Sort By" dropdown being hidden with one video, it feels more natural to also hide the grab bar.

Did not test playlist with 1 items only
Now grab bar hidden like sort control

LGTM!

Should we enforce the same behavior in list mode to keep the UX consistent?

[PikachuEXE]

I think this PR is necessary to avoid the jumping around thing, not on list mode side
And user can't use both mode at the same time...
