Describe the bug

How to reproduce the bug?

1. Headover to the website: https://grapesjs.com/demo.html.
2. Clear the canvas for a simpler demonstration.
3. Drop in a text element from the 'Blocks' section.
4. Select the dropped in text element, and select 'Style Manager', expand 'Typography' section.
5. Paste the Hex Value: '8ceb34'. This will update the text color to green in the GrapesJS canvas.
6. However, when we view generated CSS, or export as zip, the missing '#' sign will be missing and the color won't be applied.

What is the expected behavior? Either, the color shouldn't be updated in the canvas if the '#' is missing, giving the user a false impression that the color is being applied or the '#' should also be added to the Export to zip, or View Code capability.

What is the current behavior? Current behavior is that the color applies in the GrapesJS canvas, giving the user the False impression that it works, but upon export or viewing Code, it is not generating proper CSS.
