Str: 1. Open this: data:text/html,a<div>-</div> 2. Get the document accessible. 3. Call IAccessibleText::textAtOffset(0, IA2_TEXT_BOUNDARY_WORD). Expected: (0, 1, "a") Actual: (1, 2, "<embedded object>")

I'm seeing this in ATK/AT-SPI2 as well.

So, this looks like its a layout / keyboard navigation bug. starting before the a if you hit control right arrow you are told next word starts after the '-', but if the cursor is after the '-' then control left says the previous word starts just before the '-'.
