Some additional context:

I noticed that this bug happens only if the leave insight window alert is shown. If the leave insight alert isn't shown, the back button will go back to the correct url.

The window alert logic is in:

It seems like when confirm is clicked, the url is replaced:

Clicking on cancel will result in the alert to always show, and you can see that the url is constantly being replaced:

Hey @lshaowei18 thanks for your issue and PR! This is indeed a painful bug in the common browser UX.

I'll take a look on your code by Tuesday at most, and we can work together to get it merged
