Just a little bugreport – in Firefox, the "insert image" invisible file input covers buttons to the right: https://i.vgy.me/q1sYHX.gif

Setting its width to 100% (of the parent button) fixes it. Doens't happen at all in Chrome.

I would create an issue on github, but just the "grid" component is there and this is outside of it…

Thanks for the bug report. And yes, your fix worked :). I had `inset:0` for the file input and was working on all browsers except firefox.
