Created attachment 451964 [details] Solid black WebP image Safari 15.2 and 15.3 crash when decoding certain WebP images with `window.createImageBitmap`. This happens with images that have a channel depth of 1-bit in a channel (e.g. solid color images such as https://bug-219977-attachments.webkit.org/attachment.cgi?id=421723). The underlying WebP issue was logged in https://bugs.webkit.org/show_bug.cgi?id=219977 but previous versions of Safari handled the error gracefully (logging "Cannot decode the data in the argument to createImageBitmap") and error handling in sites/apps could handle the error successfully. Since Safari 15.2, the error isn't handled and causes the tab to crash. https://jsbin.com/cetawaqudo/edit?js,output is a basic reproduction using the black square image from above.

I couldn't replicate this in Tech Preview 140 so I think this is likely a duplicate and has been fixed. Thanks!
