Description viswa 2022-06-09 09:34:13 PDT

We are trying to explore a file in Salesforce analytics environment which freezes the safari 15.5 web kit(17613) entirely and can be Brought back only after closing the browser and bringing it back . 
Note : we are going to this page from a homepage ][ homepage ——> redirect to the issue page]
Note : This issue is not reproducible when we directly land on the issue page instead of coming from a home page 


We started to see the issue recently may be from a month back(not sure of the exact time line )

We are not seeing this issue in safari technology preview 15.4 web kit(17614) , wanted to know when can we get web kit 17614 on normal safari 15.5

NOTE : This issue is completely not reproducible in CHROME and Firefox browser .

We'll need a bit more information about this problem in order to investigate.

Can we get access to the content that reproduces this? If not, can you tell us something about it? Does it use <canvas>?

If there's a crash, please attach a crash log.

If there's a process hang, run `sample` on the hung process and attach the result.
