In a mew a long word is displayed fine. I don't know how it was before, now it's contained in the box anyway.

A long word in a quote looks cut off:

The mew is completely hidden instead of being truncated. Is that intended?

I don't know what the issue in webkit with links was, but it looks fine

Works fantastically!

After creating a mew with long text, I'm taken to the mewsfeed and that very mew I just created isn't abbreviated. That's intentional, I suppose?!

Yep, the mew is only abbreviated if more than 300 characters
