Bugzilla

I've used v 70.0a1 20190727213541 for bad and  v 70.0a1 20190816094815 for good, comparing the results, it looks expectantly better. 
Verified the above on Ubuntu 16.04/Mac 10.13 / Win 10 using latest Nightly 70 2019-08-16 and latest Beta 69.0b14 2019-08-15.

Also, gave it a run on the de locale, since it is one of the locales that usually has long labels, and for de locale, the 200px regular login (comment 5) doesn't do it: it is still truncated. For the first part verification, I will mark this issues as verified and tagging :mattN to confirm that the trade-off in comment 5 is acceptable for long labelled locales.
