fix: filter in external resource pages not working
For some reason, using setFilterFixedString() doesn't seem to update the
QRegularExpression object with a new value, instead leaving it empty. It
updates QRegExp just fine, so maybe that's an Qt bug? o.O

Anyway, using regex in the filter is kinda cool actually :D
