Strange behavior when autocompleting NBT before a backslash

[Dahesor]

1. Create a new mcfunction file and paste the following command:

data modify entity @s Item set value {count:1\
}

2. Place your curser before the backslash on line 1. Press , should normally pop up an autocomplete box suggesting id and components, but it does not suggest anything.

3. Now instead paste this in:

data modify entity @s Item set value {id:"minecraft:stick"\
}

4. Again, place your curser before the backslash on line 1. After pressing , it suggests the user to enter an item id instead of other keys:
