Warning message appears in the browser console, concerning about blocked aria-hidden

Since a while, a warning message appears in the browser console, warning about: Blocked aria-hidden on an element because its descendant retained focus. The focus must not be hidden from assistive technology users..

This has nothing to do with our code or installed libraries, but is related to the core browser code.

This problem happens to every coder using the Bootstrap library, there are plenty of complains on the internet.

Bootstrap did NOT issued a new release to address the problem.

There are some solutions proposed on the internet,we should test them out and see which one applies to our cases.

IMPORTANT This is JUST A WARNING for the assisted technology (screen reader), which is NOT supported by the YDB-GUI and does NOT affect any functionality.
