Bug opening file path html file with query param

[wwwillchen]

System: Linux (Ubuntu 14.04)
opn version: 5.1.0
xdg-open version: 1.1.2

File path with query param doesn't work:

$ ~/node_modules/opn/xdg-open /some/path/index.html?hi
xdg-open: file '/usr/local/google/home/chenwilliam/lighthouse/plots/charts/index.html?hi' does not exist

File path without query param works as expected and opens page in Chrome:

$ ~/node_modules/opn/xdg-open /some/path/index.html
Created new window in existing browser session.

Regular URL path with query param works:

https://www.paulirish.com/?hi
