I have a similar issue when using android:inputType="numberDecimal" and android:digits="1234567890,."
In 1.3.1 it allowed only a single decimal separator. With 1.4.0 I can input multiple dots and commas.
Even if I set the keyListener to DigitsKeyListener.getInstance("0123456789") in afterTextChanged when the text contains a dot or comma, I can still enter dots and commas.

I can cofirm the issue. We have a lot of crashes because of that change.
android:inputType="numberDecimal" stopped working and even if you set allowed digits there - user can type to inputDecimal field "_" "-", "+" - different signs that are showing up on the keyboard. It's not GBoard only issue, confirmed also on other keyboards.

I can also confirm that bug after update androidx.appcompat:appcompat to 1.4.0 version keyListener or android:digits in XML work unpredictably.

For example that code allow to write allow characters like ` ' ` or ` ` although they should be prohibited.
   <androidx.appcompat.widget.AppCompatEditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:digits="123456,."
        android:inputType="number"
        tools:hint="@tools:sample/lorem" />

A similar behavior is observed  for set keyListener to eg. DigitsKeyListener.getInstance("123456")

For fast workaround i reverted to 1.3.1 version, but if you need this particular version until it will be fixed you can try override onCreateInputConnection.

    Don't wrap NumberKeyListeners for emoji
   
    All subclasses of NumberKeyListener do not allow emoji to be input, and
    wrapping them breaks locale setting inside of TextView, which is visible
    as a change in input filtering behavior.
   
    Fixes: b/207119921
    Relnote: "Fixes issue with all NumberKeyListener subclasses introduced
    in appcompat 1.4.0 that allowed unexpected characters such as
    punctuation to be input (b/207119921)"
    Test: Manual & ./gradlew :appc:appc:cAT
