JetBrains: Force recreation of JCEF browser on every modal show

Created by: philipp-spiess

This is a workaround for #34773 (closed): On Mac OS, the web view is empty after opening and closing the popover repeatedly.

We work around the issue by forcing a recreation of the JCEF browser window whenever we open the popover.

Note: This fix is only meant to be temporary since it increases the modal opening times drastically and adds noticeable lag.
