My testers and I have somewhat frequently run into a "Timer already
canceled" exception when working with filters. There's no consistent
repro case, unfortunately, but it's happened to somebody else in the
past when they used the Label component, so I'm pretty convinced that
this issue is still lurking around.
I've sent you a screenshot that displays the stacktrace, as reported
by a user. Both single filters and filter chains are affected.
