Describe the bug

PYWB seems to be stripping out part of the URL when a timeline page is requested. For
example:
https://webarchive.nationalarchives.gov.uk/*/https://www.arcgis.com/apps/op sdashboard/index.html#/f94c3c90da5b4e9f9a0b19484dd4bb14
loads a timeline for
https://www.arcgis.com/apps/opsdashboard/index.html
Each instance shown is for index.html and not index.html#/f94c3c90da5b4e9f9a0b19484dd4bb14

Steps to reproduce the bug

1. Open this url in your browser:
   https://webarchive.nationalarchives.gov.uk/*/https://www.arcgis.com/apps/opsdashbo
   ard/index.html#/f94c3c90da5b4e9f9a0b19484dd4bb14
2. Click on the link dated 02 April 2020.
3. Initially a page with the url:
   https://webarchive.nationalarchives.gov.uk/ukgwa/20200402132156/https://www.arcg is.com/apps/opsdashboard/index.html starts to load. Note that the string after the # symbol has been stripped out.
4. The page does not load but redirects to this url:
   https://webarchive.nationalarchives.gov.uk/ukgwa/20200328185042/https://www.arcg is.com/sharing/rest/oauth2/authorize?client_id=opsdashboard&display=default&respo nse_type=token&expiration=20160&redirect_uri=https%3A%2F%2Fwww.arcgis.co m%2Fapps%2Fopsdashboard%2FpostSignIn.html&locale=en- gb&state=%7B%22redirect%22%3A%22https%3A%2F%2Fwww.arcgis.com%2Fap ps%2Fopsdashboard%2Findex.html%22%2C%22portalUrl%22%3A%22https%3A% 2F%2Fwww.arcgis.com%2Fsharing%2Frest%2F%22%7D which displays as a blank page.

Expected behavior

I'd expect the timeline page to show the correct URL timeline and allow visitors to view the history of capture for this specific URL - and not strip out the final part of the url.
