Attachment: Different-width-height-shown-in-editbox-of-boxmodel-content.png

Steps to Reproduce:
1. Start latest Nightly (e.g. Build ID:20170324030205)
2. Go to about:home
3. Open Inspector > Computed
4. Select #aboutMozilla in markup
5. Click width/height on boxmodel-content

Actual Result:
Different width/height is shown. (It seems #aboutMozilla::before size?)
Please refer to attached image.


Expected Result:
Is this intentionally? If not, own width/height is shown as default when editing.

We actually have the same issue with margin/border/padding etc...

If a pseudo-element defines a value for any of those properties, and the element itself doesn't, the editing session will pick up the value from the pseudo element.

We should just use multiline strings here
