Bug 162471 – AX: iOS: Tapping <input> in Safari zooms in a bit when page has max scale = 1

• Status: RESOLVED
• Resolution: FIXED
• Component: Accessibility

[Nan Wang]

We were ignoring force always user scalable for input field but we missed a case where web authors sometimes set maximum scale to 1 instead of user-scalable=no.

Actually those tests were failing on my local machine after moving to a different place :(

Maybe "maximumScaleIgnoringAlwaysScalable()"

I literally cannot parse "allowsUserScalingIgnoringForceAlwaysScaling"

This seems wrong. Shouldn't this return m_viewportConfiguration.maximumScale() ?

> Source/WebKit2/WebProcess/WebPage/ios/WebPageIOS.mm:2553
> +    information.maximumScaleFactorIgnoringForceAlwaysScaling = maximumPageScaleFactorIgnoringForceAlwaysScaling();

Can we use "ignoringForceAlwaysScalable everywhere?

I'll try to rename this with ignoringForceAlwaysScalable

I'm not an expert on this but I copied the logic from WebPage::maximumPageScaleFactor()

>> Source/WebKit2/WebProcess/WebPage/ios/WebPageIOS.mm:2553
