Voice mode doesn't seem to work in canvases. If I have a text box in a canvas, I can't use voice mode to enter text into that.
Basically I have a canvas that allows me to add comments on a drawing, but I can't use voice mode to enter text into the comment text box highlighted in red here.

首先，在 Windows 10 上使用版本 1.0.10 和 /chat 路径，在 GitHub Copilot 应用中重现该问题。添加一个画布评论文本框，将其置于焦点状态，然后测试语音模式；当听写的文本能够像在普通文本字段中一样输入到该文本框时，即表示完成。
