1221996 - Element picker doesn't cancel "Measure a portion of the page" and vice versa

Status: NEW

(DevTools :: Inspector, defect, P2)

Description

[arni2033]

STR:   (Win7_64, Nightly 45, 32bit, ID 20151102030241, new profile)
1. Open devtools on this page, press Ctrl+Shift+O, check "measure a portion of the page" in options.
2. Click element picker, move mouse over the page content
3. Click "measure a portion of the page" button
4. Move mouse over the page content

Result:
 It's not clear at all which tool is "active"; nothing indicates that
 (hint: element picker is "foreground", "measure a portion of the page" is "background")
 Also, if I enable inspecting anonymous content - then at the top of the page I see label
 "svg#measuring-tool-highlighter-elements.measuring-tool-highlighter-elements"

Expectations: 
 Element picker should cancel "Measure a portion of the page" and vice versa

Looking at bug 1192737, I think there should be a general solution for some group of buttons in developer toolbar
