Executing the min size of the block image properly.

Suggested merge commit message (convention)

Fix (image): The block image smaller than 50px should be resized to the minimum size. Closes #9300 .

It looks OK but it breaks the resizer logic

I guess we'd need to replicate the same min-width 100%  logic on the JS side somehow. I'm not sure if this is worth the hassle, though. WDYT @magda-chrzescian ?

@oleq It actually didn't break it, this is the way it used to work. At least on the inline images branch, even stranger things happen on master ;)

It escalates when you set the block image size to a very little value and then convert it to the inline image - it doesn't have the min-size, so the image size changes significantly.
I was about to add a separate issue to address this problem, but I guess I could fix it in this PR. WDYT?

I see no good reason to postpone the fix you proposed and mix it up with anything else. Let's have another issue with that. Can you create one?
