STR 1:

1. Create a new custom field.

4. Hover over the Text icon to view the instructions.
   ER: Number of 'rooms'
   AR: Number of \'rooms\'

On subsequent visits to the custom field list panel, hovering over the Text icon reveals:

Can you check if these two edits resolve it for you? One removes escaping of values inserted in the text input, which also resolves the regular tooltip display. The second edit resolves the tooltip display after saving when the language strings have not yet been reloaded from the db.
