fix: ending portal loop without processing its flags

[slaesh]

since the yield was AFTER processing the flags (connect/stop)..
AND we were modifying the loop-criteria, the loop could end BEFORE we had processed our flags!

SO, yield before and there is no need to modify the timeout at all :)

HI @slaesh

Please clarify and post some MRE to explain what's wrong and the bug this PR fixes, so that anybody can duplicate the issue and know the benefit of the bug fix.

Not enough with just some words.

Thanks,
