Comment 2 Hercules Hjalmarsson 2022-07-20 13:44:28 PDT 
By running API tests with command:

run-api-tests TestWebKitAPI.WKAttachmentTests.CutAndPasteAttachmentBetweenWebViews

The timing out issue persists before 252672@main. 

However, I was able to bisect the regression point to 252672@main by running bot commands taken from the bot queue:

download-built-product -> extract-built-product -> run-api-tests --release TestWebKitAPI.WKAttachmentTests.iWorkAttachmentWithoutPasteboardActionLoadsThumbnail

download-built-product -> extract-built-product -> run-api-tests --release TestWebKitAPI.WKAttachmentTests.CutAndPasteAttachmentBetweenWebViews
