Hitting backspace in a sign activates shift on your keyboard.

Put the summary of the bug you're having here

I expected that hitting backspace on the keyboard while typing in a sign would cause the letter to be backspaced and then I could continue typing lowercase letters.
Describe what you thought should happen here

Instead, when I hit backspace, my keyboard, regardless of if the character I had backspaced was capitalized or not, would automatically activate shift, so that, unless I hit shift again, the next letter I typed would be capitalized.

I was typing in a sign, hit backspace and found that, annoyingly, the character I typed was pseudo-automatically capitalized, because the shift key was automatically activated by the backspace.

1.) Enter a creative world
2.) Place a sign
3.) Begin typing in the sign
4.) Hit backspace within the sign on letters you just typed
The keyboard should auto-hit shift.
