I feel a bit nit-picky creating an entire topic for this, but I’m wondering about the thinking behind the new min-height of 30px on the base `.btn` class? ([added here](https://github.com/discourse/discourse/commit/e844fa537090bc2e80d8470c38a215dfa7857210#diff-689419c27839146782821d1c1d093928R19)).

Before I go through and make a bunch of CSS changes to buttons in different plugins I don’t want to be 30px height, just thought I’d check to see if that’s going to stick around.

Yes there is already an issue with the back button on the vertical timeline, for example.
