I managed to find a workaround for this bug, by inserting a 'TremoloSpanEvent / STOP by hand inside the quotation. Attached the .ly and the .png to show both buggy and worked-around behaviour.

For the examples I sent, 2.20 gives the same result as 2.21 (and any previous version, as far as I know). I had also tried with cueDuring but that didn't work either: no tremolos unless a "real" note follows in the quotation.

Lilypond still reports these warnings/errors (line numbers apply e.g. to the s1 quotes):

tremolo-quote-event.ly:26:5: warning: unterminated chord tremolo

programming error: Grob direction requested while calculation in progress.
continuing, cross fingers

tremolo-quote-event.ly:26:26: programming error: ly:stem::calc-length called but will not be used for beamed stem.
     \repeat tremolo 16 {
                          c32 d } |

Can I do more to help pinpoint the errors?

Good morning list,

when I end a \quoteDuring after a \repeat tremolo { ... }, the tremolo
beams are missing or distorted. If the quotation has nontremolo music
afterwards, there is no issue.

I didn't find a workaround. I tried adding a grace note or a
zero-duration note in the quotation, to no avail.

I would love to have a workaround as long as this has not been fixed.
You need to set quotedEventTypes to include tremolo-event. See:

Huh.  Why wouldn't that be the default?  This report triggered a Deja vu with me; I thought it was fixed previously?  Or was this some other kind
of event recently added?
Apologies David, it is indeed now included in the default. I think I was remembering the same from a previous problem I encountered. Rutger - I'm not sure what is going on here.

Quoting tremolo repeats works correctly in 2.20 but didn't work in 2.18 (and also not in 2.19.83 if I remember correctly). For the record, I used the following in my files, in version 2.18/2.19 (this is the same solution that is used by default in 2.20)

   \context {
     quotedCueEventTypes = #'(
   \context {
     \override StemTremolo.beam-thickness = #0.35
