MediaViewer provides a bunch of boilerplate texts in its
share/download/embed panels. It is currently impossible to read this texts
without copying them into another application (such as a text editor): the
textboxes are very small and only show the first few characters, and they
get automatically refocused and keypresses are captured by other handlers
and used for global behavior (such as prev/next), so really to only way to
scroll the text is having a touchpad. This is annoying for the experienced
user, and makes it harder for the inexperienced one to understand the
purpose of the text.

Agreed.

While most of these design decisions were taken in order to maximize the
ease of copying the text, and that is a worthwhile goal, there should be a
way to just read the text. Maybe the textbox could expand when selected...

I think the virtue of these supplemental features (e.g., trying to force all of the text in the text area to be highlighted) is pretty dubious. Is there a credible indication that users are incapable of, or have difficulty with, copying text from a text area themselves? Is extra assistance really needed here?

I don't see how this is resolved. The boilerplate for the file mentioned in the description looks like this:

The main purpose of the embed code is to be copied as is. For that purpose we want to show enough to provide a general idea of what it is but not too much in order to avoid it distracting form the rest of the settings (especially with the more verbose HTML tags).

For example, in the last step of the upload wizard, the information to embed the image in a wiki is presented in a single line where not all the content is visible at once:

As I understand it, users copy and paste the content to a wiki page and keep editing it there.
Can anyone detail some example scenarios when inspecting the content or selecting part of it would be useful?

IMO it inspires more confidence. I reading the text, deciding it's useful and pasting to pasting, reading and deciding whether it was useful. I don't have strong feelings about it though.
