Support of SELECT HTML tags broken in browser
It seems that the support of Select HTML tags is broken in latest versions of browser (problem detected on OS v79, browser v40.1).
When user clicks on a Select control, the browser briefly displays the list associated to the control but it immediately disappears.
The issue can be reproduced with many different websites (e.g. https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_optgroup , https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/select )
