Show more "stroke" dash properties

I’ve noticed that even in Dev Mode, properties for a dashed stroke do not show in the CSS or properties panel.

For example, say you have this path:

image

Suggestion

I’d love to see the properties for some of the following (or something similar for free Viewers):

<line stroke-linecap="round" stroke-dasharray="4 6"/>

Context

Currently, only the colors and thickness are displayed.
