Width of select tags via Chosen are set to 0px

As suggested by comment #9, patch #4 fixed list widths in our admin theme, but it ended up breaking some widths in our front-end theme, because the !important tag was overriding our front-end css list styling.

Submitting interdiff and patch #11, which moves the proposed styling fix to the chosen.claro.css file.

We had a related problem after upgrading to D10 with Claro theme, the contents of the Chosen select was overflowing the box, but this patch #11 also fixes it.

I tried the latest patch #11 but for me it doesn't work when its a chosen-container-single

So I investigated this issue and found that some how when Minimum width of widget is not set in the Config. by default a inline style is set that is width: 99px.

I created a fix by setting a default to auto when no width is configured at Drupal end.
MR11 will be the fix for this.

Changing this to "Needs review" because I believe it requires further investigation and review before it can be implemented.
