What type of issue is this?

Permanent – Occurring repeatably

Is this issue blocking you from using Enso?

• Yes, I can't use Enso because of this issue.

Is this a regression?

• Yes, previous version of Enso did not have this issue.

What issue are you facing?

After clicking a dropdown entry, sometimes the node selection is rendered in hovered state until the next time the node is hovered and un-hovered. The problem occurs when the clicked entry is far enough down the menu that once the menu closes, the pointer is over the graph background.

Expected behaviour

If after closing the dropdown menu the pointer is no longer over any part of the node, the node should stop being rendered as hovered.

How we can reproduce it?

After the dropdown is removed from the DOM, we receive a spurious pointerenter event. There is no corresponding pointerleave.

The problem seems to be caused by a Chromium bug: https://issues.chromium.org/issues/40156858

We need to find a workaround. I have compared mouseenter/mouseleave, and they exhibit the same bug.
