1544428 - Setting window.location.hash to an empty string on a site without a hash causes a popstate event

Status: NEW

(Core :: DOM: Navigation, defect, P3)

Description

[Dennis Schubert [:denschub]]

Attachment: Simple test case

The attached testcase has a button setting the location hash to an empty string via window.location.hash = ''; and an alert box on onpopstate.

If you open this testcase without a hash in Firefox and click the button, the URL changes from testcase.html to testcase.html#, and a popstate event is fired. In Chrome, the URL is not changing and no event is fired.

This difference actually resulted in a webcompat report about a misbehaving site. Filing this into Firefox::General, because I have no idea where this would fit.

Kicking this to Document Navigation? Please feel free to put it somewhere else more appropriate.
