Bootstrap classes work great on canvas but not in the style manager.

I set the bg-danger background color class for heading. styles applied in canvas but not in style manager.

The StyleManager sees the CSS rules imported in CssComposer module, so if you're simply using the config.canvas.styles option, those style rules are not imported.

@artf If I import bootstrap in CssComposer then it slows down editor loading

Well yeah sure, that is expected, but show some metrics and the example of how you import it.
