Text substitutions not working

Text replacement is a way of making a string be automagically replaced with another string. For example, I can set up a text replacement where the string "BRB" is replaced by the string "Be Right Back".

I set up text replacement on Mac but even though it works everywhere else, it doesn't work on an app called Anki, which is based on Qt. It doesn't work whether I use the native text replacement functionality  of macOS or I use a third-party text replacement app.

See below for how to reproduce:
—
1. Go to System Preferences -> Keyboard
2. Choose "Text" tab
3. Create a text substitution from "foo" to "bar"
4. Open Anki's Add Card dialogue
5. Type foo
Result: foo doesn't get replaced by bar.
Notes: "foo" gets correctly replaced by "bar" in the Notes app
Notes2: text replacement from 3rd party apps (i.e: Typinator) also doesn't work as expected (text gets replaced partially)
I don't know if this was happening with previous versions of Anki as I just started using text substitutions today.
