Sublime Text autocomplete in different windows?

Question

css

Hello! Tell me how to make in Sublime Text so that there are hints in different windows. For example, my screen is divided into 2 parts, in one html file, in another css.
I create a block with a class for example class="example", and when I start creating a class in css for some reason the autocomplete (hint) does not appear. Maybe something needs to be turned on? I searched on the Internet, but most likely entered the wrong one.

I found a solution, maybe it will be useful for someone. It turns out that since version 3019 this function was disabled, it’s not clear why, in my opinion it’s much more convenient.

Well, I also installed All Autocomplete, but without the settings above it will not work
