feat(web): KeymanWeb does not activate when a Select field is triggered/selected

First of all, thanks for the great software.

I am using keymanweb 15.0.272 plugin on my website. The keyboards are working fine on input fields, but they are not triggering on the select field. Normally, the select field responds to the keypress and navigate the selection accordingly. How do I achieve this behavior in KeymanWeb using a custom language keyboard.
