Selected text invisible in markdown code block

[wrjlewis]

Steps to reproduce

1. Write a markdown code block with one or three back ticks
2. Send message to the room
3. Try to select text within the code block, you cannot see a highlighted section of test representing your selection

Outcome

What did you expect?

To be able to see which text I have selected, as you can outside of code blocks

What happened instead?

The text is still selected, but it's invisible to the user, which creates a guessing game as to whether you selected the text successfully / accurately.

On MacOS the problem is harsher because you don't have the pins at either side of the selected text. Though even on iOS, you get the pins, but not the highlighted text section between.

Unfortunately that is an underlying UIKit fault and we need to drop down to UIKit for text messages for mention pill support.

I am able to easily reproduce the problem in a separate test app

let text = NSAttributedString(string: "Oi oi", attributes: [.font: UIFont.systemFont(ofSize: 20) , .backgroundColor: UIColor.green])
textView.attributedText = text
