            Bug ID: 245539
           Summary: Office.com becomes practically unusable on iPad (and
                    maybe other devices)
           Product: WebKit
           Version: Other
          Hardware: iPhone / iPad
                OS: iOS 15
            Status: NEW
          Severity: Major
          Priority: P2
         Component: Page Loading
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: nadav.bar.lev at gmail.com

### 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
