UserAgent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36

Steps to reproduce the problem:
1. open the attached test.html
2. open devtools
3. reload the page
4. press Ctrl-Shift-O to invoke "Go to symbol"
5. type "first", observe
6. delete the text you've typed and type "somefun", observe

What is the expected behavior?
* "first" is the first in the list
* "someFunction1" is the first in the list

What went wrong?
* "first" is absent
* "IrrelevantFunctionSeekOrMissEKGFreqUnderflow" is the first in the list

Did this work before? No 

Chrome version: 60.0.3112.113  Channel: n/a
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: Shockwave Flash 26.0 r0

As for the second observation, I suggest to prioritize results matched as:
* prefix +10 weight
* contiguous match +5 weight
* letter case match when the user typed in different letter cases +20 weight

P.S. The feature always worked this way since it appeared in M59 as far as I can tell.
