The "hotkey-hint" class name used internally in
d66f2d900f conflicted with the
preexisting class name for hotkey hints into popovers, introduced in
80ff3d8da5.
Given that the new class is for a styling of hotkey hints designed for
use in tooltips, it was a bad name anyway, so just rename it to
tooltip-hotkey-hint. We rename the related cluster of variable names
to match this.
The second line of a multi-line tooltip generally desctribes the
additional information which helps the major text, i.e. the first
line of the multi-line tooltip, hence it would be a good idea to
add italics styling, to differentiate it from the main title. We
describe a simple ".italic" class for the same.
We also add a shorter line height to this description using the
".tooltip-inner-content" class.
We make the tooltips of the button in the top row consistent.
This includes -
* Removing the bold formatting from the "Go to conversation" tooltip.
* Converting the "Expand compose" tooltip to Tippy.
