When resistFingerprinting is enabled, alt+letter JS keyboard hotkey bindings don't work

Caused by firefox masking the keys state when privacy.resistFingerprinting is set to true. Seems like the Mozilla devs don't see this as a bug because they don't expect privacy.resistFingerprinting to be enabled by default. On librewolf it is enabled by default so it will probably break a number of addon and website shortcuts as discussed in the upstream issue.

A workaround is to set privacy.resistFingerprinting to false. I'm assuming that disables more than just the Alt/Shift keys spoofing, so it's not a fix.
