[Evolution] Multiply replied message causes massive delays in composer editor

Evolution: 3.40.4 (3.40.4-2.fc34) Fedora Core

Does anyone else get a severe delay in the composer when replying to a message that has been bouncing back an forward multiple times?

I have a message to a support group that has bounced back and forth umpteen times, with all the earlier messages being indented and preceded with coloured vertical bars. As I type a reply (this is top replied, so older messages are unedited below and carry the full message history), the composer will just stop for minutes at a times. The keyboard appears to die (but it does buffer) . Replying to old, multiply replied messages, becomes almost unworkable. I can get around the problem by initially editing out (deleting) the indented earlier replies. So it seems the delay is in what the editor is doing with the 'old text'.
