The Bug:

The string of text "(+DATA)" displayed in item tooltips when copying a block with DATA is untranslated and untranslatable.

Steps to Reproduce:

• Place down a sign, write something on it, and click Done.
• Use Ctrl + middle mouse click on the sign.
• Hover your mouse over the picked up sign item in your inventory.

Notes:

• Attempt to search for the existence of this string in https://github.com/Mojang/bedrock-samples/blob/main/resource_pack/texts/en_US.lang.
• Take note as to whether or not the string of text "(+DATA)" is untranslatable.
