Bug 191857 – [iOS] Scrollbar size in iOS platforms

• Component: Layout and Rendering
• Status: NEW

[Manuel Rego Casasnovas]

As discussed in bug #191656 it might be needed that scrollbarLogicalWidth() and scrollbarLogicalHeight() returns zero on iOS.

Some weird issues on iOS caused that the patch for #191656 got rollout, to make it pass all tests in iOS and iOS Simulator.
To fix it temporary we added a "#if !PLATFORM(IOS_FAMILY)" there.

Does scrollbarIntrusion() do what you want?

I guess you can just use layer()->horizontalScrollbarIntrusion()?

The tests seems to render fine for me when running directly in the Safari simulator, so I wonder whether it's something specific to the test runner.
