Hints don't show for tiny inputs (react-select)

I'm using react-select on a site we're building and for some reason none of the inputs are fable. It uses a regular non-readonly not-disabled not-hidden input.

I finally tracked this down mystery: https://github.com/philc/vimium/blob/17fb86e02971948f90215934cbe5417674364a29/lib/dom_utils.coffee#L124 - apparently vimium mandates that inputs must be at least 3px wide? However, the react-select lib hard codes its input to be just 2px wide (and via an inline-style) 😞

Is there any reason for this 3px mandate? Could we reduce it to 2? Or 1? Or maybe make it based on the area? Or if there's a really good reason for this, should I go bring up an issue over in the react-select repo?

Start with lib/dom_utils.coffee at line 124, where Vimium filters very small inputs, and reproduce the behavior with the 2px input used by react-select. Check the existing comments and hint-detection flow before deciding whether the size threshold should change. Done means the intended treatment of tiny inputs is agreed and the react-select case behaves accordingly without unwanted hints.
