v8: Richtext editor view source code editor should get focus

[christophnz]

Bug summary

After clicking the View Source Code icon in the Richtext editor, the code editor opens, but doesn't get focus, so if I start typing or paste, the content still goes into whatever field last had focus.

Specifics

Umbraco v8.0.1
Reproduced in Firefox 66 and Chrome 73

Steps to reproduce

• Put the focus (cursor) in any text field or the richtext editor
• Click the View Source Code button
• Type or paste some content
• Click Close
• The typed/pasted content is in the text field or richtext editor that last had focus

Expected result

The code editor should get the focus to avoid accidentally editing content that is hidden behind the code editor

Actual result

I accidentally pasted HTML code into a text field that was hidden behind the code editor and still had focus.

Yeah, that seems annoying 🙈

I've marked this as "Up for grabs" so that you or someone else coming along could create a pull request for it.

Relates to #5220 as well.
