R2L lines display the continuation glyph on the left.

Sorry, I don't understand what you tried. Please show a screenshot.

They should set the fringes to 1-pixel width, then. Or make their
frames 1 character wider. Sorry, I simply didn't find any other
reasonable way to make the display code sane and the results on the
screen plausible. Breaking bidirectional display is a no-starter
nowadays, I certainly won't agree to that. Motivated volunteers are
welcome to find a better solution.
(Once upon a time, Emacs couldn't display continuation glyphs on GUI
frames at all, until someone convinced me to add this feature. The
rest is history.)

Suggestions for how and where to document this, and patches to that
effect, are welcome.
