Respect autocorrect="off" for Windows touch keyboard in TSF

Chrome 149 makes Chrome on Windows honour autocorrect="off" for the Windows on-screen touch keyboard (via the Text Services Framework), matching the behaviour already present on other platforms and in other browsers.

why it exists

The HTML autocorrect attribute lets authors tell the browser whether to apply automatic text correction to an editable element. Setting autocorrect="off" is important for fields where verbatim input matters — code editors, username fields, password-visible inputs, search boxes that accept technical terms, and so on.

On Windows, Chrome routes touch-keyboard input through the Text Services Framework (TSF). Before Chrome 149, the autocorrect="off" attribute was not forwarded to TSF, so the touch keyboard would still apply its built-in autocorrections regardless of what the page specified. Chrome 149 closes this gap: TSF is now instructed to suppress autocorrection when the focused element carries autocorrect="off".

shape of the API

No new API. The change is a behavioural fix to the existing autocorrect content attribute.

Attribute	Element	Effect in Chrome 149+ (Windows touch)
`autocorrect="on"` (default)	`<input>`, `<textarea>`, `contenteditable`	TSF autocorrection active — same as before
`autocorrect="off"`	`<input>`, `<textarea>`, `contenteditable`	TSF autocorrection suppressed — newly fixed in Chrome 149

example

<!-- Code editor: prevent the touch keyboard from "correcting" keywords -->
<textarea autocorrect="off" autocapitalize="none" spellcheck="false"></textarea>

<!-- Username field: no autocorrect, no autocapitalise -->
<input type="text" name="username"
       autocorrect="off" autocomplete="username">

<!-- Normal prose field: autocorrect on (the default) -->
<textarea></textarea>
