Status: UNCONFIRMED

(Core :: DOM: Selection, defect)

Description

Attachment: index.html

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Safari/537.36

Steps to reproduce:

1. Open the attached HTML file.
2. Use the mouse to select text anywhere in the document.
3. Use the keyboard to expand the selection (e.g., using the arrow keys, shift + up/down).
4. Ensure the selection includes an element styled with user-select: none.
   Change the direction of the text selection (e.g., from up to down or vice versa).

Actual results:

When the selection reaches the boundary of the user-select: none element, it stops removing the text selection.

Expected results:

The text selection should continue seamlessly across the boundary of the user-select: none element, even when changing the direction of the selection. The selection behavior should not be interrupted by the presence of elements with user-select: none.
