[EuiSelect in EuiPopover] Focus trap requires two clicks when focus is on select

[snide]

To replicate

1. Go to EuiExpression docs https://elastic.github.io/eui/#/forms/expression
2. Click first expression.
3. Change the dropdown
4. Two clicks are required to exit the trap

This is not something specific to EuiExpression and I was able to replicate in the popover docs by adding a new select.

cc @mikecote since this is an issue he runs into often in Kibana.

Possibly similar to #2490

I don't think this is still an issue, but would like a second opinion

1. The repro steps involve an EuiSelect not an EuiSelectable, so I may be misunderstanding
2. It's possible that the switch to react-focus-on fixed this ([EuiFocusTrap] Use react-focus-on #3631; in July 2020)

I went back to an old PR to test: https://eui.elastic.co/pr_3630/#/forms/expression and the issue existed. I checked the referenced pr https://eui.elastic.co/pr_3631/#/forms/expression and the issue still existed. But I checked the most recent build (v.37.5.0) and the issue does not exist. So yes, I'd consider this fixed, just don't know when or how. 😆
