TypeError in useFeatureFlags()

[matthew-white]

Sometimes, but not always, I see an error like this when I open the browser console:

TypeError: undefined is not an object (evaluating 'n.key.toLowerCase')

The line that's flagged is:

central-frontend/src/composables/feature-flags.js

Line 27 in acd5cf6

if (event.key.toLowerCase() === 'w') {

I'm not able to reproduce the error consistently. Looking at the code, I'm wondering whether it's possible for event.key to be undefined when event is a keydown or keyup event.

It'd be nice to resolve this error, but I don't think that it's user-facing. Even after seeing the error in the browser console, I'm able to press W+F to toggle Web Form buttons in Frontend.

I've noticed this after clicking certain buttons:

• Dropdown in the navbar on the right
  • Edit profile
  • Log out
• Cancel button on the "Reset password" page

I'm noticing this when I visit central without logging in (saw it on staging, too)
