**Initial research:**
From basic code inspection it looks like WPF gets into a state where there is a highlight for text selection that specifies an offset that is outside of the line metrics. Perhaps something is being done on an event handler that modifies the text or the text selection and that is causing the mismatch. In any case, we can guard against this relatively simply.
