Tabstop is set to 8 for javascript files (.js, .es6)

[tchar]

Does this bug happen when you install plugin without vim-polyglot?

No

Describe the bug:

In vim for js files (also es6, did not try all of them) tabstop is forced to 8.

I also tried setting let g:polyglot_disabled = ['javascript'] before the plugin loads and it still forces my tabstop to 8.
If the polyglot_disabled option works for javascript this means that tabstop is forced by polyglot.

According to this they don't force any tabstop so it should be from polyglot
With .py files tabstop is forced to 4 (not set) (which is expected).

To Reproduce:

In case you need it

Vim version: version 8.1.2269
OS: Ubuntu 20.04

Here is the .vimrc that can reprodue the issue

set nocompatible
set tabstop=4

" The following line does not resolve the issue so I commented it out
"let g:polyglot_disabled = ['javascript']

call plug#begin('~/.vim/plugged')

Plug 'sheerun/vim-polyglot'
"Plug 'pangloss/vim-javascript'

call plug#end()

Swaping the plugins issue is no more and tabstop is back to 4

As far as I know, vim-polyglot uses vim-sleuth and it might be the case here. I also saw this in vim-sleuth's doc https://github.com/tpope/vim-sleuth#notes

If your file is consistently indented with hard tabs, 'shiftwidth' will be set to your 'tabstop'. Otherwise, a 'tabstop' of 8 is enforced.

Looks like I had to set softtabstop/shiftwidth to make it work. Thanks for the suggestion.

It can't have something to do with vim-polyglot because I've stopped changing setting tabstop long time ago. It's only sleuth that does that, not vim-polyglot's implementation of it. If you encounter this issue again, please attach file you are editing, and result of :verbose set sw ts, thank you!

I've added change that automatically sets shiftwidth to tabstop if it is greather than it
