Error setting tab width for prettier

[xiavn]

Hi there,

When attempting to set the tab-width option for prettier using the command line arguments ( --tab-width 4) an error is returned:

● Validation Error:

Option "tabWidth" must be of type:
number
but instead received:
boolean

Example:
{
"tabWidth": 2
}

In addition I've noticed on your online example site, if you attempt to change the tab widths it appears to fail, and the svg side of the site stays grey like it does when loading.

Thank you! It is definitely a bug, I think it is easy to fix, I am open to PR 😊
