Description

Type: Bug

When debugging C++ code it's possible to be sitting at a break point and the mouse hovering over a function can cause it to execute. This can unintentionally break debugging sessions due to unintended mouse movements.

Research direction

Start by reproducing the issue with the reported C++ debugging setup: pause at a breakpoint and hover over a function. Investigate the extension's hover and expression-evaluation behavior, then verify that mouse hovering no longer executes code or disrupts the debugging session.
