Non-chrome browser optimization

[IsoPhoenix]

Overview

Questable seems to have some unresolved functionality issues that occur specifically in Safari at the moment. We should fix the bug below, and also do an extensive test of the frontend functionality in Safari (and maybe other browsers) to make sure everything works as intended.

Bug: Create Task form (Safari)

When trying to create a task as a teacher, the form for creating a task seems to be stuck on the date picker; you cannot select or edit any other fields. The form behaves as expected in Chrome.

Functionality walkthrough in other browsers

Click through Questable's functionality in other browsers (particularly Safari) and note down any functionality bugs that pop up. Fix the bugs that you can and let Matthew know if there are any particularly troublesome ones
