This is not a duplicate of #9644 -- but it's perhaps tangentially related

I'm using multiple boxes side by side in VSCode, so

This package seems to polyfill window.Promise, regardless of whether window.Promise already exists. This is causing problems as we are using and relying on our own polyfill (bluebird.js), but this is being replaced if I call new EditorJS().

Bug Description:

There are a number of logs of the form console.error(e) in the debug module, and those errors end up appearing in the console as [object Object]. They should be replaced with something like console.error('<Method> failed:', e);

To quote eishiya from the Tiled forum:

When highlighting a layer, have an option for a light colour as the fade colour. The dark default doesn’t work well with dark tiles, as they blend in.

Could probably be added alongside the grid color configuration.
