Bug 243286 – AX: AccessibilityObject::accessibilityVisibleCharacterRange misses the first line of a paragraph split across pages (part two)

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

[Tyler Wilcock]

In https://bugs.webkit.org/show_bug.cgi?id=242880, we made a change that prevented this issue in some (in reality, only a few) cases. However, after further testing, I've found other cases that are not fixed.

do we want the MaxX here of the rect rather than the origin?

I don't think so as maxX includes width, which we expect to not be consistent (because paragraphs will extend different lengths down the line). So it wouldn't be a good indicator that we've crossed a viewport boundary.
