Description

[arni2033]

>>>   My Info:   Win7_64, Nightly 49, 32bit, ID 20160526082509
STR_1:
1. Open url [1]
2. Open debugger
3. Prettify the script
4. Add breaking on "click" event
5. Click on page
6. Click "Step in" several times to debug the script

AR:  Debugger always highlights the 1st line as current
ER:  Debugger should highlight the actual line during debugging


[1]
data:text/html,<script src="data:text/javascript,
onclick=function(){F()};
function F(){console.log(G())};
function G(){return window.val};
window.val=3;
"></script>
<script>
document.querySelector('script').removeAttribute('src');
</script>

Prettify is not always successful for this case. Please provide a working version if you think it may be a regression.

Can't reproduce because I can't prettify this, which is slightly concerning but not quite surprising as this is quite a convoluted example.

To help investigate the issue of the first line being highlighted if a script is deleted, it would be helpful to have an example that doesn't confuse the debugger and can actually be prettified.
