This has noticeable misbehavior when framerates are low (in my case this
sometimes happens when CPUs are throttled and compilation is happening),
as now a batch of x11 events can contain events over the span of 100s of
millis. So in that case, key press repetitions with quite normal typing
are skipped.
Under normal operating conditions it can be reproduced by running this
and quickly switching to Zed:
> sleep 1; for i in {1..5}; do xdotool type --delay 5 "aaaaaa "; xdotool
key Return; done
Output before looks like:
```
aaa
aaaaa
aaa
aaa
aaaa
```
Output after looks like:
```
aaaaaa
aaaaaa
aaaaaa
aaaaaa
aaaaaa
```
This behavior was added in #13955.
