[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

Since this unstable test blocks fixing bug 1578337 and not running on a lot of platforms, we should convert it back to mochitest. I'm currently struggling with timing issue of resizer rendering on macOS.

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

Attachment: Bug 1581206 - Reconvert browser_bug629172.js to mochitest

Currently, we can use chrome process's shortcut key with
EventUtils.synthesizeKey() with enabling "test.events.async.enabled" pref.
So, we should reconvert it to a mochitest for making it more stable.

Oddly, when I try to run this test as test-verify on macOS, it permanently
fails rendering resizer of <textarea> elements immediately after creation.
Therefore, this patch disables this test in test-verify on macOS.
