### Steps to reproduce Browse to Office.com Login with a Microsoft account Click on Word/Excel/PowerPoint Repeat step 3 for 4-5 times The page becomes unresponsive and the UI freezes for a decent amount of seconds ### Expected behavior As per my comparison to other browsers, Google Chrome and Microsoft Edge (both Chromium based browsers) are able to render this webpage perfectly fine, providing the smooth and expected user experience I expected WKWebView to provide. ### Actual behavior The page becomes laggy, freezes the UI for a few seconds and makes the use of Office.com practically impossible. ### Device & build information Device: iPad Air (3rd Generation) / Simulator - iPad 9th Generation Build version: 105 / Local build of main at 613707d
Thank you for the report! Could you please clarify the scenario? - Are you observing this with your own WebKit build in iOS Simulator? How are you building and running Safari for this? - What is "105 / Local build of main at 613707d"? 613707d is not a hash in the WebKit repository AFAICT. - Can you reproduce with stock WebKit?

@Alan - you did recent fix around office.com, do you think this bug is still applicable or fixed?
