            Bug ID: 195362
           Summary: REGRESSION: (r242181) API test
                    DragAndDropTests.ExternalSourcePlainTextToIFrame is
                    Timing out
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests

The following API test is timing out on iOS debug

DragAndDropTests.ExternalSourcePlainTextToIFrame

Probable cause:

This began timing out with https://trac.webkit.org/changeset/242181/webkit. I confirmed this using command:

run-api-tests DragAndDropTests.ExternalSourcePlainTextToIFrame --ios-simulator --debug

on r242181 which produces a timeout. Running this on r242180 produces no timeouts.
