The selection works, but it is impossible to do if you open the tooltip via click. This is probably related to how we hide the tooltip: https://github.com/bpmn-io/properties-panel/blob/main/src/components/entries/Tooltip.js#L93C23-L93C39

CSS is good but it solves the issue only partially. The rest needs to be fixed upstream though.

@jarekdanielak for the properties panel part, this may be useful: https://developer.mozilla.org/en-US/docs/Web/API/Selection/containsNode

[jarekdanielak]

Let me fix the properties panel part and reopen this when it's ready.

We could also merge this, and open a separate issue of "Tooltip closes unexpectedly when trying to select" (closing #4834).

Let's merge this and look into bpmn-io/properties-panel#399 for more improvements on the tooltips.
