Still happening on 1.93.0
Hi thank you for opening this issue. Could you please explain the issue in more detail, when you talk about the sticky part of the tree, what exactly are you referring to? A screen recording showing the issue would be helpful.
This issue has been closed automatically because it needs more information and has not had recent activity. See also our guidelines. Happy Coding!
Sorry, it took me a while to get back to this and create a demonstration of the problem (a couple of tweaks to the tree-view-sample). Can this be re-opened, or should I create a new issue?
Hi of course you can just comment here. I will reopen the issue. I think our bot closes our issues too preemptively.
Thanks ! I forked the samples here: and made a couple of edits to the tree-view-sample: I've 'mark' and 'unmark' commands to the file explorer part of the tree-view-sample, which sets a folder to 'marked' or 'unmarked'. The mark command uses the $(check) icon, and is only enabled if a folder is unmarked. The unmark command uses the $(close) icon. and is only enabled if a folder is marked. In other words, if you click the check icon it turns into a close, and vice versa. Now, if you scroll the file explorer so that a folder is 'sticky' (i.e.

beneath the view header and not in the scrolling region) the icon can still be clicked but doesn't change. Video attached.
Thanks for reporting this, this is a good catch. Sticky Scroll doesn't rerender in his case because it doesn't think something changed.
Moving this issue to October
