[BUG] The chat prompt grabs the input when trying to maximize the main panel via keyboard shortcut

What's Wrong?

When hitting the keyboard shortcut to maximize the panel (View: Toggle Maximize Panel):

• In Cursor.AI's IDE the sidebar expands to occupy have the width of the editor
• In VSCode the extension grabs the input and transfers the focus to the chat's prompt (textbox)

Notes:

1. Defining a different keyboard shortcut yields the same result.

1. The problem does not persist when the extension is not visible on screen (e.g. by closing the extension or by opening a different text document in the same panel, making the extension tab hidden).

1. The problem also does not persist when using the Claude Code CLI panel. It happens only with the VSCode UI extension.

What Should Happen?

The main panel (terminal, problems, output, debug console) should maximize to the full height of the editing area.

N/A

Steps to Reproduce

Hit the "View: Toggle Maximize Panel" shortcut.

Edit: Clicking the UI button has the same effect - the extension hijacks the operation.
