Not sure there is anything actionable here but the stack seems mostly list view. Could be originating from the explorer though. CC @joaomoreno

Yeah I don't know what to do with this. @benibenj, do you see anything that pops up regarding the latest changes done in the tree/list?

It's very hard to tell from this trace. As it's more than 2 weeks old, it would only line up with sticky scroll. However, as the trace includes setChildren, I doubt that this is caused by Sticky Scroll.

I'm seeing this in a Jupyter notebook every time I try to 'Rename Symbol'. What debugging info do you need?
