Instant code (view) updates on design (element) changes

In current version, when there’s change of element in design view, the code will only be updated on (design view) blur. Meaning that user needs to click other element or somewhere in design view then the code in code view will be updated. If I make a text Bold from design view, then directly click on the code view, the code will not be updated with b tag. I need to click somewhere in design view after I make a text bold then the code will be updated in code view.

Can this be improved so that the code will instantaneously updated right after changes in design view.

Thanks
