Description Daniel Bates 2019-12-11 14:08:13 PST 
Load a web page with the following markup:

[[
<!DOCTYPE html>
<html>
<body>
<p id='text' contenteditable>The quick brown fox jumps over the lazy dog.</p>
<script>
getSelection().setBaseAndExtent(text.firstChild, 0, text.firstChild, 0);
</script>
</body>
</html>
]]

The request a UIWKDocumentContext for rects with word granularity. Then UIWKDocumentContext.textRects is always the empty array. But it should be non-empty.

Added tests when the caret is at the beginning or end of the text and the text has leading or trailing non-breakable space.
