The default size of the dialog box created by ui.browseableMessage is too small. #20429

Brief summary

The default size of the dialog box created by ui.browseableMessage is too small.

To be precise, it seems that wx.html2.WebView does not expand its best size based on the content.

The current total size of the dialog box is less than 200x200 pixels, and the WebView is even smaller, making it almost impossible to display any content. (Although scrollbars are present, this size is practically useless.)

Steps to reproduce

Displays a browsable message, for example, by pressing NVDA+x twice.

Actual behavior

The message dialog box is very small.

Expected behavior

Display the browsable message dialog in an appropriate size.
