Now Discord is not scaling correctly or showing the entire page. I am using Safari 11.1.2
This comes after realizing I can't comment on YouTube or see the notifications on YouTube in Safari 11.1.2. I don't know if these two issues on Discord and YouTube are the result of the same problem.
It just seems like sites are breaking all of a sudden on Safari 11.1.2. But, I don't know if that is true. I tested this out in Firefox and I don't have the problem with that browser.
