Attachment: screencast 1 - Url opened in a new tab is lost if I cancel page loading.webm

>>>   My Info:   Win7_64, Nightly 46, 32bit, ID 20160103030302
STR:
0. Disable cache: Open about:preferences#advanced -> "Network" -> "Limit cache to 0 MB of space"
1. Open the following "data:" url in a new tab (really, I only need a source to drag a link)
>   data:text/html,<textarea cols="70">https://bugzilla.mozilla.org/show_bug.cgi?id=1236528
2. Select the url in <textarea>, hold Shift, drag-n-drop the url at the right side of selected tab
   [it will start loading in the foreground]
3. While the active tab (opened in Step 2) still shows title "Connecting..." (gray spinner),
   hold Escape key to cancel loading
4. Right-click the tab, click "Reload Tab"

Result:       Title displays "New tab". Urlbar is empty. Page is actually about:blank
Expectations: After Step 4 the url from Step 2 should start _loading_again_

No, this is a UI issue.  The UI is what forgets the URI; the core code never got as far as having it loaded, so doesn't have it at all.
