Chrome on Android misaligns/cuts off select form-control-lg/form-control-sm

Created by: dracos

[I saw #23347 (closed) but thought this was different enough (doesn't affect text inputs, for one thing) that it might be solvable separately.]

When viewing a <select class="form-control form-control-lg"> on Chrome (60) on Android, the text is not vertically centred; it is too low and so the bottom can be cut off. It is also not vertically centred when using <select class="form-control form-control-sm">; this time it is too high. This can be seen by viewing the documentation page at https://getbootstrap.com/docs/4.0/components/forms/ on Chrome on Android, or in desktop Chrome by opening dev console and activating mobile mode, and looking at the select examples. I've provided a screenshot of my phone looking at the docs here.
