[Reg 4.7->4.8] Debugger looks like being interrupted when it isn't

Open a project, set a breakpoint, start debugging.
Hit the breakpoint and continue.
Then switch the debugger view to "preset", and back to the debugger run.

The debugger jumps to the location where it previously had stopped, and shows a yellow arrow before that line, as if it were interrupted at that location. But the application is actually still running, not interrupted, the backtrace is completely grayed (as it should).
