Colemak keyboard layout's left-hand backspace is also acting as Caps Lock

[Tialae]

I have installed Ubuntu with the default English (US) Qwerty keyboard layout and I added the English (Australia) Colemak keyboard layout through the Settings app (as per the screenshot attached). This is for the in-built laptop keyboard on the Lenovo ThinkPad X1 Yoga Touch.

The bug is that the CapsLock key, which is meant to be remapped to a Backspace key on the Colemak keyboard layout, acts as both the CapsLock AND the Backspace, when the Colemak keyboard layout is active. This means that backspacing a single time deletes a single character AND also toggles Caps Lock.

The expected behaviour is that the key acts only as Backspace when the Colemak keyboard layout is active.

The output of 𝚡𝚙𝚛𝚘𝚙 -𝚛𝚘𝚘𝚝 | 𝚐𝚛𝚎𝚙 𝚇𝙺𝙱 is

 _𝚇𝙺𝙱_𝚁𝚄𝙻𝙴𝚂_𝙽𝙰𝙼𝙴𝚂(𝚂𝚃𝚁𝙸𝙽𝙶) = "𝚎𝚟𝚍𝚎𝚟", "𝚙𝚌𝟷𝟶𝟻", "𝚞𝚜,𝚞𝚜,𝚞𝚜", ",𝚌𝚘𝚕𝚎𝚖𝚊𝚔,", ""

I hope a fix can be found soon :)

I have since found that executing in Terminal, the command
  𝚡𝚖𝚘𝚍𝚖𝚊𝚙 -𝚎 "𝚌𝚕𝚎𝚊𝚛 𝙻𝚘𝚌𝚔"
is a temporary workaround to fix this behaviour; however, I would definitely think this issue should be fixed so it works out-of-the-box for new users.
It's a very problematic behaviour for one's primary backspace to be also toggling caps lock, affecting daily typing.
