Constantly getting 'irregular whitespace' when using ||

[Cuel]

Hi. I'm using Atom with this editorconfig

root = true
[*]
end_of_line = crlf
insert_final_newline = true
trim_trailing_whitespace = true
charset = utf-8
indent_style = space
indent_size = 2

.eslintrc

{
  "extends": ["standard"]
}

EDIT:
I'm not entirely sure when it happens. It seems to be when strings are involved, e.g this will always cause it

let a = {raw: {channels: [{channel_name: 'test', cid: '979'}]}}
let root = a.raw.channels.find(v => v.channel_name === 'test' || v.cid === '979')

The above always results in Irregular whitespace not allowed at line xx
Happens on both Mac and Windows
The position is always just before the ||
I can fix it temporarly by going to the position, pressing backspace and space again.
It works until I open the file again. I'm not sure if this is a standard, eslint or atom issue.

Is this a known issue?

I can't think of how this could be caused by standard.

It's worth noting that on OS X typing ALT+SPACE inserts a non-breaking space character (which looks the same as a space, but isn't a normal space). Maybe that's the issue?

No idea how the issue could come back when you re-open the file. Sounds like your editor is modifying files automatically when they're opened.

It's not alt+space, that's for sure. I'm using editorconfig which is the only package capable of editing files when opened afaik. I'll keep looking

You could open the file in a hex editor to see what got inserted
