Can't copy and paste the background colors of the visual editor

I have updated Anki 2.1.49 version to New version(Q5, Q6 2.1.54) today. (Windows 10)
Whenever I copy and paste something with background colors in the visual editors of the both Browser and the Add, it is impossible to bring the background colors. This phenomenon appears in the New version (Q5, Q6 2.1.54), not in the previous version (2.1.49).
So, I have done these using HTML editor, but it’s inconvenient.
I hope that this problem will be fixed.

I’ve added this to Background color is stripped when pasting between fields in day mode · Issue #1964 · ankitects/anki · GitHub
