wpviews: copying all content doesn't inlude shortcodes

[iseulde]

Selecting and copying all the content or part of the content, including a view, doesn't copy the shortcode, but the text inside the view (if there is any text).
[When you select an individual view, it copies the shortcode.]

Not sure if we can fix this in the current wpView implementation. Maybe better to wait until TinyMCE implements the "widgets" feature and try to fix it there if it still doesn't work.

Similarly to #28070, fixed by the block editor as of WP 5.0.
