Interacting with signs when holding a brush will sometimes break the sign.

Steps to Reproduce:

1. Open a world and switch to creative
2. Place a sign (any type, including hanging)
3. Select a brush in your hotbar
4. Interact (right click) with the sign whilst holding the brush to open the text edit UI
5. Exit the UI (press esc)
6. Repeat steps 4 and 5 several times if necessary

Observed Results:
The sign has a chance of breaking when interacting with the sign, usually happens in 3-5 attempts, but sometimes happens in the first interaction, destroying the sign

Expected Results:
The sign never gets broken when right click / interacting

Notes:

• This bug does not seem to occur when the sign is locked (using honey comb) so appears to be an issue with the sign editing interaction.
• The bug does not appear to occur in survival, probably because the sign cannot be quickly broken
