Sleeping my Mac always end browser extension session

I’m using Bitwarden browser extension on Microsoft Edge running on Mac.
According to Vault Timeout Options | Bitwarden Help & Support timeout is based on last time you interact with Bitwarden. However, sleeping my Mac for 1 hour always causes vault to timeout, even when timeout is set to 4 hours.

Are you quitting your browser app also, or are you leaving it running. Quitting the browser app will always force you to login or unlock again, regardless of the timeout lock period.

I run BW on Safari and FireFox on three Macs, and I have not encountered this problem, in case that is helpful.
