Debug console cannot print long values

• put a breakpoint here:

  vscode/src/vs/workbench/browser/parts/editor/editorWithViewState.ts

  Line 155 in c8e2fd7

  if (!editorViewState) {

• in the debug console type JSON.stringify(editorViewState, undefined, 4)
• 🐛 the output is only shown partially

We do limit the length of strings shown in the debug console; it shouldn't be the case that accidentally evaluating the wrong data can freeze the UI or extension host.

However note that you can copy(JSON.stringify(editorViewState, undefined, 4)) which will get the entire value

That makes sense but the limit seems very conservative. The same values printed in chrome dev tools without any issue.

I'm not sure the release this was reported on, but shortly prior to this issue the budget was bumped to 100,000 characters from 1,000. Devtools limits their initial display to 5000 characters, so I think that's the case.

Playing around, it seems like numbers much above 100k seem to cause performance hangs, it 'costs' roughly 100ms per 100k characters on my macbook. However I now show message hinting that the user can still copy the value to their clipboard:

I think this should be sufficient for the issue; let me know if not
