294419 - The input cursor is misshapen in text input boxes and textareas when page has international text.

Status: RESOLVED DUPLICATE of bug 288839

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

Description

[Neil MacMillan]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

When a page has non-standard-ASCII text in the body or title (or possibly other
places), the cursor in text entry areas has a dot attached to it.

Example:
- Page with international text: http://www.csc.uvic.ca/~nrqm/cursor_intl.html
- Same page without international text:
http://www.csc.uvic.ca/~nrqm/cursor_nointl.html

The first example has Arabic text in the page body, and the second example has
just standard ASCII text.  Click on the textarea box to see the misshapen cursor.

If it doesn't work for others, here is what I see:

Reproducible: Always

Steps to Reproduce:
1. Go to a web site with international text and a text entry area.
2. Click on the text entry area.
3. That's pretty much it.

Actual Results:  
The entry cursor had a few-pixel lump growing out its side.

Expected Results:  
The entry cursor should just be a vertical bar.

I'm told it happens in Netscape, too.  It doesn't happen in Internet Explorer or
Opera.

I can see this. It looks like the cursor equivalent of a mouse dropping.

I also see the described behaviour; the caret is rendered incorrectly.

Or is it incorrect? I believe that caret is the BiDi caret to show which
direction (left-to-right or right-to-left) the language is in. So I guess this
could be expected behaviour?

That's a clever idea!  If that's the case though, it still works incorrectly. 
In the Arabic text, the cursor is unchanged.

As an addendum to the original report, the cursor also renders incorrectly on a
page with international text when using caret-browsing mode.  The page-wide
caret has the funny dot thing.  It also doesn't change between standard ASCII
text and Arabic, as it should if it's supposed to indicate text direction.

-> BiDi
-> Trunk
