Please restore the code block type that was removed last week

There was a third type of code block that seems to have had its button removed last week. It looked like this:

It's different from that kind produced with three backticks (```), ctlr+alt+shift+b, or ctrl+alt+shift+c. It's better than either of those for my use cases, because it accepts longer blocks of text, and it automatically truncates (note the "Expand" text at the bottom of the screenshot I posted). This makes it much more useful for sharing long blocks of text copied out of routers while working with a group of people to troubleshoot a problem.

The remaining code block types do not have the same functionality.

I see that Teams is still able to render the ones I used last week. Is there a keyboard shortcut I can use to create this type of block?

Thanks;
