Thanks for clarifying. The reason for this behaviour when editing map object styles might be that perhaps it was intended for users to be working within the map window exclusively whilst applying new styles hence why when records are being selected from the browser window and the map window is no longer active then toggling the style does not take effect.
However, perhaps sometimes users may want to select specific records from the browser window and if a user has a tiled view in place such as in the screenshot below, where certain records are selected from the browser I can see where this kind of scenario you described may be encountered. In this case, the map window would need to be activated by clicking once in the map window tab before updating the style.

Perhaps this behaviour is something which someone from our Engineering team would be able to provide some feedback on as to whether it is working as designed? 🙂
