Preparation:
* Start a debug session on a class with a moderately long source (at least three editor screens).
* Put two breakpoints somewhere in the first screen and somewhere in the third screen (the one in the first screen should be reached first)
* Start debugging
* When the first breakpoint is hit create a pinned watch near it
* Continue debugging
* When the second breakpoint is hit press F8 to step over the statement

Observed behaviour:
* The editor scrolls upwards to the first screen to make the pinned watch visible

Expected behaviour
* The editor stays in the third screen and highlights the next statement line



I'm not sure if this bug belongs to the editor component, reassign if not.
