some of the message text vanishes if message direction is set to RTL


(Core :: Layout: Text and Fonts, defect)

Not set

In recent builds, messages which, upon loading, have their messages set to RTL
direction (e.g. due to the use of BiDi Mail UI -
are displayed with some of the text wiped out (screenshot to follow). I have not
experienced this happening otherwise. In 1.8a2  (I think) and backwards this
does not happen. It also does not happen with tbird 0.8 or 0.9 .

BTW - There is a possibility this also happens with the browser, I just haven't
tried setting dir=RTL on page load there.
there should be more text to the right of the displayed text, in most of the

Note that selecting the missing text causes it to appear.

Although this bug can be worked around - selecting the text and de-selecting it,
or scrolling down and back up - this bug is of extremely high visibility for
users who read RTL mail, therefore I suggest blocking 1.8a6 .

As per David Glazman's suggestion, cc'ing dbaron.
as per David Barron's request, attached the text of the message in the
screenshot. Encoding should be Windows-1255.

I was hoping this would be fixed before I would have to type in this
dependency...  :-(

Eyal, can you help us identify the day of the regression by looking through
nightly builds at and finding
the build where it broke? This may help us identify the problem checkin faster. 

If it worked in 1.8a2 then it would be a pretty easy binary search between the
July 14 nightly build and when you reported this bug (November 9).
Unfortunately, not right now, since I am about to be offline for a long while
due to various problems I won't go into... but I'll try to get this done within
a few days, maybe a week. Mano, Prog: if you can reproduce this, please oblige
Asa instead of me...
too late for 1.8a6. blocking-

Not seeing the bug with 1.8a4, i.e. with build 2004-08-17 09.
Seeing the bug with a build from November 1st.

Also, I've found a sure way to reproduce the bug (with BiDi Mail UI installed):

1. Open MailNews
2. Set the composition prefs to compose HTML messages (rather than text messages)
3. Set the BiDi Mail UI prefs so that the default composition direction is RTL
4. Open a new message composition window
5. Enter the text "abc" (it should be aligned to the right since the direction
is RTL)
6. Press Ctrl+Shift+X to change the direction to LTR
7. The "abc" vanishes, and the cursor appears at the left part of the window, as
at the position it should appear at after entering "abc".
8. Use the arrow keys to move left and right - the text remains invisible but
the cursor movement is appropriate
9. Switch to another window, then switch back. The text is now visible again.

Note that if instead of step 6 you change the paragraph dir using the dir
buttons in the formatting bar, the bug won't manifest itself.
Mass-assigning the new rtl keyword to RTL-related (see bug 349193).

Is this issue still relevant?
Not seeing this any longer (using TB 7.0b).
