Platform accessibility concerns about materia

[cayb0rg]

Header:

• Links are read as "visited"
• Current tab order is Materia logo -> profile section ->navbar. This may need to be in the order of viewing (Logo -> Navbar -> Profile section)
• Logout button is not tab reachable

Widget catalog:

• Features for each widget are read a single string
• Search bar doesn't have a descriptive label

My widgets page:

• Widgets are not tab-reachable
• Widget icons do not have alternative text
• Search bar does not have a label

Widget detail page:

• Breadcrumb arrow is aria-visible
• Demo navigation buttons (left, right, dots below) need labels
• Collaborate, Make a copy, Delete, and Edit settings buttons are not tab-reachable

Scorescreen:

• Compare With Class score view is screenreader navigable when closed
  Profile page:
• Profile pictures need alt text
• User tags such as "staff" and "support" may need a descriptive header visible to screenreader
  Creator:
• Save History and Import Questions links are not tab-reachable
• Save History saves not are tab-reachable

May need an aria-live region to read out updates to reflect player changes, updates, or errors (e.g. hitting "Save" in player settings would say "Settings saved", etc.)

All pages are still tab and screenreader-reachable when dialogs (such as collaborator, save history, question importer, etc.) are open
