Bug 38487 – Rich text editor does not scroll horizontally when trying to edit a long string of text

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: HTML Editing

[Diana Kimball]

Rich text editor does not scroll when editing a word longer than the width of the input field, which results in user not being able to see what they are modifying.

1) Input a long string of characters into a rich text edit field--such as the "new message composition" field for Yahoo! Mail--until the characters exceed the width of the input field. (Note: this does not repro in GMail, where text wraps once it hits the far edge of the input field.)
2) Place insertion point at the beginning of the string of characters, and press "End" on the keyboard or attempt to use arrow keys to navigate toward the end of the string.

Expected result: Rich text editor scrolls right, revealing the end of the string and moving the insertion point accordingly

Actual result: Rich text editor does not scroll horizontally in response to "End" or arrow keys, which results in the user not being able to reach the end of the string via keyboard commands alone.

Note: This is especially problematic for navigating long URLs in rich text edit fields via keyboard commands.
