Sometimes, in a large clientside webapp, it's necessary to identify which line of code has scrolled the document with a scrollTo() call (or if this is even the cause of the scroll*).
Is there any Chrome DevTools feature which will break JS execution on a window scroll? I'm imagining a feature similar to the DOM Breakpoints feature.
* Scrolling can also happen for other reasons, such as text input in an offscreen <input>.

You can use a JavaScript event listener breakpoint. In the sources tab for Chrome developer tools, locate the "Event Listener Breakpoints" and then the "scroll" breakpoint is located under "Control".
Add a conditional breakpoint by right clicking a line number, selecting Add Conditional Breakpoint , and entering an expression. Note: Because the conditional breakpoint simply evaluates an expression, you can add useful logging statements within the expression.
