I can't reproduce on macOS with 62b10, b11, b13  or 63a nightly. Can you doublecheck on a separate machine? Why is the screenshot so warped? Are there any errors in the browser console?

> - not present in either the narrator themes: light, sepia, dark.

What does this mean?

Attachment: updated image

- indeed it's not reproducible on macOS (confirmed on 2 different machines with macOS_10.11,  macOS_10.13);
- updated the image, it wasn't any error at fault just the save format;
- in the Type controls section, you can change the theme of how the page is displayed. In the last info I was referring to that.

Could not find a proper regression range.
In an attempt to find it: 43.0a1 (2015-09-10)  - did not have the narrator/narrate option at all. 

@Gijs is there any chance that this part was missed or not addressed at all during the initial development on Linux?

Redirecting to Eitan, who implemented this.

Comment 5

[Eitan Isaacson [:eeejay]]

Word tracking relies on platform features that don't exist in Linux.

Specifically, Speech Dispatcher does not fire word boundary events.

This bug can probably be closed as WONTFIX, unfortunately.

Thanks, I'll close the bug then.
