Tabs misbehave when opening repeated links

Summary:
Tabs misbehave when opening repeated links.

Reproducible:
Always.

Steps to Reproduce:
 1. Paste a link in a tab
    (if using the home page link [1], one may simply copy it and skip to 3);
 2. Press Enter;
 3. Create a new tab;
 4. Paste link used in 1 into the new tab address;
 5. Press Enter.

Expected results:
New tab opens pasted link.

Actual results:
Previous tab is selected. No navigation is performed in new tab.

Additional Information:
By the experienced behavior suggests that tab manager uses URI as
unique identifier. This may not be a good approach for several
reasons:
 * One may open same link to perform later processing (for example,
for navigating to a children page afterwards);
 * Often, same URIs correspond to different content (in session-based
navigation and other non-REST approaches);
 * One may simply want to open same link twice (why not?).
