Broken in Chromium/Chrome

Problem

Chromium (Ubuntu 22.04) is not working anymore!

The palette is not synchronized from the IndexedDB, console logs:

tslib.es6.js:118 Uncaught (in promise) Invalid lex string

Promise.then (async)
step @ tslib.es6.js:120

While testing in the local network with a (mobile) Chrome, adding colors is broken aswell (as that test was executed from my phone, no detailled error messages, might be the same issue).

Research

• This SO thread suggests that the error is raised because of a missing catch() while dealing with promises.
• this may be solved during #42 , as failures during database access should end up in a notification, so there will be catch() blocks anyway.

It's working, without real consideration...
