New item modifiers for charms and That Which Was Taken not available on Firefox browser

At least half of the new modifiers that appear on charms and That Which Was Taken are not searchable when I am using Firefox.

If I populate the search form by clicking the "Filter by Item Stats" button, the mods will show as "Unavailable Stat".

For example, this is what the search form looks like after populating it from the Cyclopean Refuge Racecourse Map. https://imgur.com/a/zHI4nqJ

This problem does not occur at all for me when using other browsers.
