-apple-system as default font in visual editor

The default font selection in the visual editor is -apple-system instead of the font I have selected as the default.

If I turn off the classic editor there is no font selection drop down.

If I turn off the WeaverX Pro plugin there is no font selection drop down.

If I have WeaverX Pro and the classic editor running together with no Jetpack they work fine.

This specific default font selection drop down is a function of the classic editor in conjunction with WeaverX Pro. Turning off either of those plugins results in the problem going away simply because the default font selection drop down is no longer present.

When I turn on Jetpack the default font selection defaults to -apple-system.

The only active plugins in all screen shots above are classic editor, weaverx pro and jetpack.
