monaco-editor version: 0.9.0
Browser: Chrome
OS: Windows
Steps or JS usage snippet reproducing the issue:

let z = 0.5;
editor.domElement.style.transform = `scale3d(${z}, ${z}, ${z})`;

When clicking inside the editor there are like "invisible blocks" overflowing from the left side.

Edit: Also some lines are impossible to click, the cursor jumps either to the line above or below but not to the expected line.
