Unable to add spans in RStudio Visual Editor

[jonbry]

I'm not sure if this is the right place as it is may be a feature request more than a bug, but if I try to add a span using Visual Editor, it escapes the brackets, which makes it show up as text in the output. There is a div shortcut option when using ^/ but I didn't see one for spans as well.

If I enter the following in Visual Editor:

[tester]{style="font-size: 0.8em"}
\[tester\]{style="font-size: 0.8em"}

The results in Source Editor:

\[tester\]{style="font-size: 0.8em"}
\\\[tester\\\]{style="font-size: 0.8em"}

Is there another way of doing this so I don't have to switch back and forth between editors? I understand why this may be the expected behavior, but it would be nice to have a span option under the /^ shortcut to avoid going back and forth between editors.
