Node.js 16 breakpoints bind to the end of the block, not the line specified

[kyrylkov]

Issue Type: Bug

With Node.js 16 try to set a breakpoint on any line of an async function. In multiple cases the breakpoint doesn't bind to the line but instead to the end of the block.

This is confirmed to happen in 1.55, 1.56 and 1.57 without any extensions installed. This is also confirmed to haven only with Node.js 16.x. Everything works fine with Node.js 15.x.
