The bug

Relates to MC-206550.

When water or lava drip into cauldrons, the subtitles are missing. This is MC-206550. However, looking into the en_us.json file, we can see that these subtitles are included:

"subtitles.block.pointed_dripstone.drip_lava_into_cauldron": "Lava drips into cauldron",
"subtitles.block.pointed_dripstone.drip_water_into_cauldron": "Water drips into cauldron",

However, the word 'cauldron' in both of these subtitles should be capitalized.

How to test

1. Locate your Minecraft folder
2. Go to versions -> version of your choice, and extract the contents of the .jar file
3. Open the folder assets within the extraction of the .jar file
4. Navigate to minecraft -> lang -> open en_us.json
5. Locate the strings above, and notice the non-capitalized words
