Bug 253752 – AX: -[WebAccessibilityObjectWrapperMac attachmentView] should only be called when needed

• Component: Accessibility
• Status: RESOLVED FIXED

[Tyler Wilcock]

There are several places where we repeat calls to -[WebAccessibilityObjectWrapperMac attachmentView] in close succession rather than storing the attachment view in a local variable and re-using it. This is wasteful in ITM as each call requires a separate, synchronous round-trip to the main-thread.

I think we can get rid of the isAttschment variable and just use whether attachmentView is nil

AddObject: attachmentView ?: wrapper

Would it make sense to get rid of isAttachment() and just have a attachmentView() that returns nil when it is not an attachment?

Yes, that's a good idea! Will put on my to-do list for a future patch.
