            Bug ID: 202518
           Summary: imported/w3c/web-platform-tests/2dcontext/drawing-text
                    -to-the-canvas/2d.text.measure.emHeights.html and
                    2d.text.measure.fontBoundingBox.html fail on iOS
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas

        Depends on: 179191

2d.text.measure.fontBoundingBox.html fails with:

FAIL Testing fontBoundingBox assert_equals: ctx.measureText('A').fontBoundingBoxAscent === 85 (got 86[number], expected 85[number]) expected 85 but got 86

which I'd be inclined to ignore, but then 2d.text.measure.emHeights.html fails with:

FAIL Testing emHeights assert_equals: ctx.measureText('A').emHeightAscent === 37.5 (got 86[number], expected 37.5[number]) expected 37.5 but got 86

which makes me think there's an actual problem, given all other platforms pass.
