Interesting. The attempt to set those styles we try to set on the anonymous
nodes in the textarea fails because the style language is not CSS. Then we
crash at:
0x413fbd1c in nsSelection::GetFrameForNodeOffset(nsIContent*, int,
nsIFrameSelection::HINT, nsIFrame**, int*) (this=0x8813d48, aNode=0x871fcd0,
aOffset=4, aHint=HINTRIGHT,
aReturnFrame=0xbfffdf88, aReturnOffset=0xbfffdf5c)
at /home/bzbarsky/mozilla/xlib/mozilla/content/base/src/nsSelection.cpp:2981
2981 result =
(*aReturnFrame)->GetChildFrameContainingOffset(*aReturnOffset, aHint, &aOffset,
aReturnFrame);
(gdb) p aReturnFrame
$2 = (class nsIFrame **) 0xbfffdf88
(gdb) p *aReturnFrame
$3 = (nsIFrame *) 0x88829a4
(gdb) p **aReturnFrame
$4 = {<nsISupports> = {_vptr.nsISupports = 0x0}, mRect = {x = -572662307,
y = -572662307, width = -572662307, height = -572662307}, mContent =
0xdddddddd,
mStyleContext = 0xdddddddd, mParent = 0xdddddddd, mNextSibling = 0xdddddddd,
mState = 3722304989}
after the following assertions:
###!!! ASSERTION: non-root frame's desired size changed during an incremental
reflow: 'first == root || (aDesiredSize.width == size.width &&
aDesiredSize.height == size.height)', file
/home/bzbarsky/mozilla/xlib/mozilla/layout/html/base/src/nsPresShell.cpp, line 898
###!!! ASSERTION: frame was not removed from primary frame map before
destruction or was readded to map after being removed:
'!PL_DHASH_ENTRY_IS_BUSY(entry) || entry->frame != aFrame', file
/home/bzbarsky/mozilla/xlib/mozilla/layout/html/base/src/nsFrameManager.cpp,
line 1006
###!!! ASSERTION: existing overflow list: 'rv !=
NS_IFRAME_MGR_PROP_OVERWRITTEN', file
/home/bzbarsky/mozilla/xlib/mozilla/layout/html/base/src/nsBlockFrame.cpp, line 4356
So the fact that the styles are not getting set is causing issues somewhere in
frame construction or editor, looks like.
Really, we should guarantee that inline style on anonymous content is set as
css, no?
Yeah, on anonymous content that we create ourselfs I agree. On XBL-created
content i'm not so sure though. I.e. xbl that comes with the webpage

Sure. But the upshot is that we need to have a way of setting the style attr
that does _not_ do that check that ParseStyleAttribute does....

crashed on Win98 using Mozilla 1.4.1, Mozilla 1.5 and current nightly BuildID
20040216
Talkbacks from 1.5: TB30484909M, TB30484793H
Testcase of Bug 234624 also crashed submitting some Enters only, but the
DocWatson Files are about double the size.

sicking, can you add such a method?

(also occurs in Firefox 0.8, see
http://forums.mozillazine.org/viewtopic.php?t=49646&highlight=contentstyletype)
I also observe that sometimes the cursor isn't rendered in form fields, and that
when you type a lot of letters the text is drawn outside the form field.
Notice that the Postbank site mentioned in the forum topic above has made a
mistake and had to use Content-Type instead of Content-Style-Type.
Unfortunately, their mistake crashes our browser...

looks good to me. Though why wasn't the div already native-anonymous? Are we
only setting that on the top native-anonymous and it doesn't get cascaded down
into the children?

It's not _yet_ native anonymous. It gets set so later, when it's returned to
the frame constructor from this method.

Checked in for 1.8a. I think we should take this for 1.7, so leaving open.

Could this please be approved for 1.7? This is a very safe patch that fixes a
crash that pages can trigger by simply including a meta element other browsers
ignore...
