Title:
  snap fails to pass chromium arguments

Status in Chromium Browser:
  New
Status in snap package in Ubuntu:
  Confirmed

Bug description:
  $ lsb_release -rd
  Description:	Ubuntu 20.04.1 LTS
  Release:	20.04

  $ snap --version
  snap    2.45.3.1
  snapd   2.45.3.1
  series  16
  ubuntu  20.04
  kernel  5.4.0-21-generic

  $ snap list chromium
  Name      Version        Rev   Tracking       Publisher   Notes
  chromium  84.0.4147.135  1269  latest/stable  canonical✓  -

  GOOD:
  $ /snap/chromium/current/usr/lib/chromium-browser/chrome --headless  --dump-dom /usr/share/doc/bc/bc.html

  produces output, while

  BAD:
  $ /snap/bin/chromium --headless --dump-dom /usr/share/doc/bc/bc.html

  fails with

  [0826/093125.490825:ERROR:headless_shell.cc(174)] Open multiple tabs
  is only supported when remote debugging is enabled.

  
  Debugging hint: I get the same error when calling

  $ /snap/chromium/current/usr/lib/chromium-browser/chrome --headless  -- dump-dom /usr/share/doc/bc/bc.html
  [0826/093139.340093:ERROR:headless_shell.cc(174)] Open multiple tabs is only supported when remote debugging is enabled.

  (note the extra space between "--" and "dump-dom".

  
  Apologies if this turns out to be an issue with snap-confine or one of its siblings!
