Add title element to Time Read to show accurate number

Read time vs Recent read time

Recent read time is within the last 60 days, read time is since the creation of your account.

@zogstrip I suggest we add a title= element here so at least on pointer-capable devices, we provide the actual time, as we do with the other numbers:

<span class="number" title="3,222">3.2k</span>

<span class="number" title="85,240">85.2k</span>

… but when I hover over read time or recent read time, there’s no title attribute

I suggest the hover could contain the actual time (if available) plus the hint of how long, e.g. 6 months = 4,380 hours so the title tag can read:

4,381 hours (all time)

and

5 hours (in the last 60 days)

from

<span class="value">6mon</span>

to

<span class="value" title="4,381 hours (all time)">6mon</span>

@nbianca can you add this one to your list?
