            Bug ID: 251558
           Summary: Relax the checks of the alpha channel of the blurred
                    stroke in
                    fast/canvas/canvas-scale-strokePath-shadow.html
           Product: WebKit

          Severity: Normal
          Priority: P2

This test is a little bit fragile with the system changes which are related to the Gaussian blur stroke. The value of the alpha channel of the stroke can be different on different releases of macOS and iOS. And this why we have three platform expectations for this test.

To make the expectation more robust and to avoid the rebase-lining it in the future, we can relax the text a little and ensure the alpha channel of the blurred stroke is between 75 and 225 instead of 175 and 225.
