jweb textarea macOS shortcuts and Chinese IME candidate window not working

I'm using a standard HTML textarea inside a jweb object in Max 9 on macOS.

I've noticed two issues:

1. Standard macOS text editing shortcuts do not work inside jweb textareas in Ableton Live

   • Cmd+A (Select All)

   • Cmd+C (Copy)

   • Cmd+V (Paste)

   • Cmd+X (Cut)

2. Chinese IME candidate selection does not work

   • Typing phonetic input works.

   • The Chinese candidate window never appears

What I've tested:

1. Max native textedit object

   • Chinese IME candidate selection works correctly

   • macOS text editing shortcuts work

2. Empty jweb page containing only:

   <textarea></textarea>

   • Cmd+A/C/V/X do not work

   • Chinese IME candidate selection does not work

Is this a known limitation of jweb on macOS, or is there any workaround to enable native text editing shortcuts and IME candidate selection?

Additional information:

• macOS 26.5.1

• Apple Silicon (M1)

• Max 9.1.4

• Ableton Live 12.4.1
