Description Jacob Uphoff 2020-03-04 09:28:28 PST

The following tests started to fail after commit r257839:

fast/forms/textarea-no-scroll-on-blur.html
fast/forms/textarea-scrolled-type.html

I was able to reproduce the failure running the test in iterations on commit r257839 and was not able to reproduce it on r257838.
