"Jumping" focus between the JCEF intances

[kshmidt-digma]

STR with Digma Plugin: 1) Open the Main Digma panel 2) Open Observability Digma panel 3) Switch to another desktop application (IDE and the plugin panels will lose the focus) 4) Click anywhere in the Observability panels

Current behavior: Both JCEF panels try to steal focus

Expected behavior: Only the panel that has been clicked on should have the focus

It seems like this is the Intellij problem, as it also reproduces with the Intellij What's New page. STR: 1) Go to Help -> What's New in IntelliJ IDEA 2) Open it multiple times in different editors side by side 3) Switch to another desktop application (IDE and the editors will lose the focus) 4) Click on one of the editors

Current behavior: Both editors try to steal the focus

Expected behavior: Only the tab that has been clicked on should have the focus
