Expected behavior

Tabbing away from an open Select should close the list of options.

Actual behavior

Tabbing away from an open Select keeps the select open. This is especially problematic when the options cover another form input or focusable element because the user doesn't see what's focused.

Getting an "Internal Server Error" once the newly created snippet loads, but you can reproduce the issue on the example page https://mdbootstrap.com/docs/standard/forms/select/ Simply open a select and press Tab to focus to another element.
