emporia_vue fails to initialize under home-assistant-snap; can't install pyemvue dependency

[curtisgalloway]

I am running Home Assistant under Snap (home-assistant-snap) and trying to use emporia_vue through HACS. This worked until the most recent update that requires pyemvue version 0.18.4; now I get the following error when Home Assistant starts up:

2024-04-09 12:48:36.799 INFO (SyncWorker_10) [homeassistant.util.package] Attempting install of pyemvue==0.18.4
2024-04-09 12:48:47.312 ERROR (SyncWorker_10) [homeassistant.util.package] Unable to install package pyemvue==0.18.4: ERROR: Will not install to the user site because it will lack sys.path precedence to pycognito in /snap/home-assistant-snap/592/lib/python3.12/site-packages
2024-04-09 12:48:47.315 ERROR (MainThread) [homeassistant.setup] Setup failed for custom integration 'emporia_vue': Requirements for emporia_vue not found: ['pyemvue==0.18.4'].

The pip command it's trying when installing pyemvue is this:

2024-03-21 10:46:20.926 INFO (SyncWorker_1) [homeassistant.util.package] Attempting install of pyemvue==0.18.4
2024-03-21 10:46:20.926 DEBUG (SyncWorker_1) [homeassistant.util.package] Running pip command: args=['/snap/home-assistant-snap/585/bin/python3', '-m', 'pip', 'install', '--quiet', 'pyemvue==0.18.4', '--timeout', '60', '--upgrade', '--constraint', '/snap/home-assistant-snap/585/lib/python3.11/site-packages/homeassistant/package_constraints.txt']

I'm assuming this is something to do with the virtual environment when running under snap, but I haven't been able to reproduce the failure by hand yet running in a shell in the snap environment.
