Can't use Ctrl/Cmd+A to select all text when option is selected

[ragulka]

Using a simple (single item) select, it seems it's not possible to select all the text in the input by pressing Ctrl+A/Cmd+A. It only seems to work when being in "search mode".

Steps to reproduce:

1. Open select
2. Type something random
3. Press Ctrl+A/Cmd+A - observe that all the text is selected
4. Now, clear the input and select an option from the dropdown
5. Open the select again, press Ctrl+A/Cmd+A
6. Observe that it doesn't select the text in the input

I would expect being able to select the text in input regardless of whether it contains an actual selected option or a search string.

Looks similar to #256. Thanks
