Allow new transitions to run even when controller is suspended

• Component: CSS
• Status: RESOLVED FIXED

[Dean Jackson]

We fixed a bug where newly created CSS animations and transitions would run, even when the WebView had explicitly suspended animations. It turns out that some content in some clients actually relied on this behaviour :(

Add a flag to toggle back to the old buggy operation.

Are these up-to-date with the code changes?

allow -> allows

> Source/WebCore/page/animation/AnimationControllerPrivate.h:114
> +    bool allowNewAnimationsWhileSuspended() const { return m_allowNewAnimationsWhileSuspended; }
> +    void setAllowNewAnimationsWhileSuspended(bool);

allow -> allows

> Source/WebCore/page/animation/AnimationControllerPrivate.h:148
> +    bool m_allowNewAnimationsWhileSuspended;

allows. might want to add a comment to explain why this is here.

> Source/WebKit/mac/WebView/WebViewPrivate.h:568
> +- (BOOL)allowNewCSSAnimationsWhileSuspended;
> +- (void)setAllowNewCSSAnimationsWhileSuspended:(BOOL)allowed;

allows
