Thanks a lot for your contribution! But, this is related to v17 branch. For now, I ported your fix to v17 branch. Thanks a again!

@mertsincan the same problem with scroller is in v18 and probably v19 as well

[mark7p]

hi @martinkasa, i just checked v18 and v19 and both are working fine. would you mind creating an issue and include reproduction of the bug?

[martinkasa]

#17102 sorry, it could be not related to your original bug. I just noticed that all virtual scroll elements got broken in 17.18.12 and the same happens in v18.
