As a QA: this bug will get downprioritised by PM to oblivion.
I kid a little, I worked with some very good PMs when we did client work who made my life much easier. Working on a SaaS though, I find them generally less than useful.
where I work it is normally easier to fix things than deprioritize to oblivion. I can fix an issue, but priority puts a dozen people in a meeting.
If it messes up the UI until you refresh, yeah, I understand deprioritizing that.
If it causes catastrophic data corruption or leaks admin credentials, any sane PM would want that fixed ASAP.
