[EuiPopover and EuiComboBox] Has issues ownFocus

[Bargs]

When ComboBox is the first focusable element in a popover with the ownFocus prop enabled you'll see the ComboBox and Popover flash briefly in the wrong spot before the popover opens completely. Also, sometimes the ComboBox won't open at all. You can see both of these issues in the gif below:

I have the same issue. Is there any workaround?

There doesn't seem to be one at the moment except for perhaps turning off ownFocus or by making the combobox not the first focusable element in popover.

The case specifically shown in the gif was recently fixed in Kibana: elastic/kibana#56222

The solution was to use the initialFocus prop on EuiPopover to target one of the header elements for focus.

To prevent this error at the EUI level, I think we'd be looking at altering animation logic or introducing render delays for popover content.

I can no longer reproduce this bug.

It's likely this was fixed by the move to react-focus-on from react-focus-lock or one of the version updates we made to react-focus-on.
Additionally, ownFocus no longer focuses the first focusable element by default (#5784), so this outcome is significantly less likely to happen even if my repro is misleading.

Closing, but anyone can reopen if the problem has not been resolved.
