Spun off from bug 1770606 as this is just one aspect of the performance problems observed there.
By maintaining a line cursor in the block for querying purposes, separate from that used during display-list construction, we can greatly reduce the overhead of a11y calling GetRenderedText on all the text frames in a large document; see bug 1770606 comment 21.
