Bug: Bracket spacing is ignored

What is the current/expected behavior?
By default, bracket spacing is true, thus I expect the following format:

import { foo } from './foo.js';

But vim-prettier is always collapsing that to:

import {foo} from './foo.js';

What version of vim-prettier are you using - (output of :PrettierVersion) ?
0.2.7

What version of prettier are you using - (output of :PrettierCliVersion) ?
1.19.1

What is your prettier executable path - (output of :PrettierCliPath) ?
prettier

Did this work in previous versions of vim-prettier and/or prettier ?
This is my first time using vim-prettier. Prettier is working as expected in other editors (VS Code).

When I save the file in nvim, it collapses the brackets. If I then check the file:

prettier --check "foo.js"
Checking formatting...
foo.js
Code style issues found in the above file(s). Forgot to run Prettier?

...then manually running prettier --write "foo.js" puts the spaces back in.

For reference, here are all my plugins:

It turns out there was an issue with coc and its config to formatOnSaveFiletypes. Removing JS/TS let vim-prettier behave properly. But since I'm using coc I switched to coc-prettier instead. Is one preferred over the other (coc-prettier or vim-prettier)?
