AX: In isolated tree mode, an empty text field's text markers point into its
placeholder
https://bugs.webkit.org/show_bug.cgi?id=323507
rdar://186747687
Reviewed by Chris Fleizach.
A placeholder stands in for text the field doesn't have, rather than text it
contains, but its
rendered text was collected into the isolated tree's text runs like any other
text. For an empty
<input placeholder="text">, AXTextMarkerRangeForUIElement on the field resolved
to the placeholder's
static text and reported a length of 4 with the string "text", where the live
tree reports the field
itself. It also meant a text-marker walk over the document would read a
placeholder as if it were
page content.
Stop collecting text runs for a text control's placeholder, so that an empty
field with a
placeholder behaves the same as an empty field without one. A field that has a
value is unaffected
either way, since the placeholder isn't rendered then.
