Hang on workspace change followed by aggressive focus shifting

[nyaray]

Body

Thanks for releasing this. I fucking love it. Anyway, to the issue.

Steps to reproduce:

1. I pressed alt-shift-2 a couple of times in quick succession to go to my second workspace and then cycle through its windows.

Expected result: Switch workspace and cycle windows.
Actual result: Switched workspace, cycled window once (I think) and hanged aerospace.

Additional info

$ aerospace -v
aerospace CLI client version: 0.19.2-Beta d246f250468fc9d427a2eb901d56794af7ac6609
AeroSpace.app server version: 0.19.2-Beta d246f250468fc9d427a2eb901d56794af7ac6609

I'm using the following binds:

alt-ctrl-1 = 'exec-and-forget aerospace workspace --fail-if-noop  1 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'
alt-ctrl-2 = 'exec-and-forget aerospace workspace --fail-if-noop  2 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'
alt-ctrl-3 = 'exec-and-forget aerospace workspace --fail-if-noop  3 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'
alt-ctrl-4 = 'exec-and-forget aerospace workspace --fail-if-noop  4 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'
alt-ctrl-5 = 'exec-and-forget aerospace workspace --fail-if-noop  5 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'
alt-ctrl-6 = 'exec-and-forget aerospace workspace --fail-if-noop  6 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'
alt-ctrl-7 = 'exec-and-forget aerospace workspace --fail-if-noop  7 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'
alt-ctrl-8 = 'exec-and-forget aerospace workspace --fail-if-noop  8 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'
alt-ctrl-9 = 'exec-and-forget aerospace workspace --fail-if-noop  9 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'
alt-ctrl-0 = 'exec-and-forget aerospace workspace --fail-if-noop 10 || aerospace focus dfs-next --boundaries-action wrap-around-the-workspace'

I've provided all 10 for your convenience in case you need to jump around a lot and just hammer it with interactions.
