>>>   My Info:   Win7_64, Nightly 50, 32bit, ID 20160726080520 (2016-07-26)
STR_1:
1. Open attached "testcase 1"
2. Open debugger, set breakpoint in script at line 2
3. Click on the page content
4. Click "Step In" in debugger

AR:  Debugger switches to line "/* we need a miracle */"
     More generally, it scrolls current script to the very end, as it tries to go to line 3857049061

ER:  Debugger should swith to line with "if" or to line with closing bracket of current function

Note: 
 It's not clear what component it is. Is it possible that JS engine reports something wrong that
 confuses debugger? Or probably debugger itself should be updated to handle this properly.
 I can't possibly know, because I don't do the development.

This is regression from bug 1261826. Regression range:

Thanks for the bug report! This looks like an issue we have seen before on the debugger frontend. We will try to confirm it. I have copied over this information to github:

Thanks for filing. I'm closing as I can not reproduce the issue and the debugger UI has changed a lot over the past year.
