login to steam, leave steam open for several days

while USING STEAM actively, steam pops up the login window saying "session timed out" requiring user to login the password and 2FA again (steamguard) internet is good, no downtime, no lossed connection, nothing changed, im Actively using my computer & steam steam has been open for several days, even while away from computer for 10+ hours

expected that steam will not log me out or timeout my session, as previously with the "old" login method steam never logged me out, even if loss of connection

Steps for reproducing this issue:

1. open steam, login to steam, 2fa steamguard
2. wait 12-24 hours without using steam???
3. a login window popup "session timed out"
