From the customer: > I am using chrome browser Version 135.0.7049.114 (Official Build) (64-bit). > Yes, I noticed this behavior in other browsers(ex. firefox) > Yes, I noticed this behavior in an incognito window as well. I was unable to reproduce this issue on my side so I am attaching a video reproduction in [the shadow ticket](https://getsentry.atlassian.net/browse/FEEDBACK-2408?atlOrigin=eyJpIjoiMzM5OGVjOWVhNWMxNDRiODlkNWRjMTMzN2JhZTEwNzkiLCJwIjoiaiJ9). ### Product Area Issues ### Link _No response_ ### DSN _No response_ ### Version _No response_
