By replacing `<span>` tags with `<div>` tags inside the tooltip's inner
content we remove the redundancy of having to use break tags to
separate the tooltip's title and it's content.
We also replace any `<p>` tags with `<div>` tags for the following
reasons:
- Since what we want to achieve are just block elements in order to
avoid the break tags, using `<div>` tags provide use with a wider
scope of use cases.
- We don't want the pause, screen readers often introduce after reading
the contents of a paragraph.
- The `<p>` tag cannot contain tables and other block-level elements.
- The semantic meaning of the <p> tag doesn't apply to the commonly
used tooltip content.
This commit replaces the mute/unmute topic button in the message
header bar with a button that allows the user to set the
visibility_policy of the topic to muted, unmuted, followed or inherit.
The button in the message header bar has an icon corresponding to the
current visibility policy of the topic.
In a muted stream:
A click on the button opens a popover with 'Mute', 'Default', 'Unmute',
and 'Follow' options.
In a not muted stream:
A click on the button opens a popover with 'Mute', 'Default', and
'Follow' options. 'Unmute' option is available only when the
visibility_policy is set to 'Unmute'.
The current visibility_policy of the topic is highlighted in the
popover.
