130530 - In textarea, caret can disappear when the line causes the box to scroll to the right

Status: NEW

(Core :: Layout: Form Controls, defect)

Description

[Russell Odom]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.9) Gecko/20020311
BuildID:    2002031104

Typing a long line in to a textarea (causing it to scroll), moving the caret to
another line, then using the arrow keys to position the caret back at the end of
the long line causes the caret to be hidden.

Reproducible: Always
Steps to Reproduce:
1. Position caret in a textarea
2. Hold down the <A> key until the line length exceeds the width of the
textarea, causing it to scroll
3. Hit <Enter>
4. Hit the left arrow key to position the caret back at the end of the long line

Actual Results:  Caret is positioned correctly (logically) but is not visible

Expected Results:  Caret should be visible

Caret becomes visible again if left arrow key is pressed (it remains visible if
caret is then repositioned at the end of the line with the right arrow), or if
something else is typed at the end of the line.

Looks to me like this may be a dupe of 130418.  Although, in this case the caret
is not visible at the end of a long line of text, and in 130418, the caret is
not visible at the beginning of a blank text field.

No, I don't think it is a dupe of bug 130418 - in that case, the caret isn't
shown; in this case, I'm think the caret is there (it appears if I click
anywhere else in the window) but just being hidden by the edge of the textarea.
