Bug 244746 – AX: Stop unnecessarily caching AXPropertyName::{LayoutCount, PressedIsPresent, DropEffects, ClickPoint, ClassList}

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

[Tyler Wilcock]

We only expect these properties to be requested by tests and automation on the Mac (so not actual AX clients), so don't do the work to cache them.

Can we put length outside the loop to reduce number of times it is called

Is there some existing map function that does this?

Fixed.

Unfortunately no. This is a DOMTokenList class rather than a Vector, and it doesn't have a map function.
