Describe the bug
I cannot cancel displaying XPUB on screen of T1. Displaying it on Trezor is an upcoming feature in Suite.

Firmware version and revision
1.12.1, 1eb0eb9

Desktop/smartphone setup (please complete the following information):
T1 (works fine on TT)

To Reproduce
Steps to reproduce the behavior:

1. trezorctl btc get-descriptor -n 0 -d
2. Click the left button - nothing happens

Expected behavior
Public key is not displayed anymore after clicking "Cancel"

presumably it's the "cancel" text that is wrong?
(the button takes you to the next part of XPUB, then to address, then to QR, etc., correct?)

[komret]

I updated the screenshot, the previous picture was confusing, sorry. The right button shows the second part of the pubkey and then hides it, as expected. The left (cancel) button does nothing.

Also, no option to show the QR code. I'd expect either hiding the pubkey on cancel or replacing the cancel button with QR code button, same as when displaying a receive address.

[Hannsek]

we should replace the cancel button with QR code button.

@Hannsek could you please take a look at #4480 (comment)?
I'll be happy to hear your opinion.
