Navigation duplicates the expression in braille #470
Description
When I enter navigation mode i NVDA, the mathematical expression is duplicated in braille.
At first, I see the last character of the expression appears at the beginning of the braille display. When I navigate using the braille display, I can see that the entire mathematical expression appears twice.
Highlight with dots 7 & 8 are set to Endpoints:
In some expressions the highlight of the first part and the last part of the expression miss the correct target.
Highlight in ASCIIMath and LaTeX are missing ( but this might be because they are not braille notations.
