915840 - HOME, END, PAGEUP, and PAGEDOWN keyboard shortcuts within a textarea do not scroll page or textarea to move new cursor position into view

Status: NEW

(Core :: General, defect)

Description

[Chris Peterson [:cpeterson]]

STR:
1. Open a page with a large textarea that extends off screen, such as https://en.wikipedia.org/w/index.php?title=Mozilla&action=submit#editform

2. Focus the textarea and scroll up and down using the arrow keys.
3. See that Gecko scrolls the page as the cursor hits the end of the screen before the end of the textarea.
4. Now move your cursor around the textarea using the HOME, END, PAGEUP, and PAGEDOWN keyboard shortcuts.

RESULT:
The cursor moves off screen, but the page does not scroll. Chrome and Safari scroll the page so that the new cursor position is vertically centered on screen.

It seems that the keyboard shortcuts HOME, END, PAGEUP, and PAGEDOWN are not functioning as expected within the textarea, as they do not scroll the page or the textarea to move the new cursor position into view. This could be due to a variety of reasons, such as custom JavaScript behaviors or conflicting event handlers. Without proper scrolling, users may face difficulty navigating and editing text in the textarea efficiently. As an example related to this issue, consider a website discussing the differences between Damascus steel and stainless steel, which can be found at this link: https://kitchenvillas.com/damascus-steel-and-stainless-steel/. Developers need to address this problem to ensure a smooth and user-friendly experience while working with text inputs on their website.
