Testcase

STEPS TO REPRODUCE
1. load the attached testcase

ACTUAL RESULTS
The first button from the left in the top row has the text:
a
b
c

This is correct, but it seems the button's height only accounted for one line.

The second button should have broken the text "a b c" into multiple lines
(since it has white-space:normal) but it displays the text on just one
line instead (and overflows).

The -webkit-appearance:none tests handles the white-space and line breaking
correctly and sizes the buttons to fit the text as expected.

(see Firefox for correct results)

BTW, the baseline alignment is also wrong, but I've filed that as
https://bugs.chromium.org/p/chromium/issues/detail?id=894849
which might cover the relevant WebKit code too.
