Instead of inserting tooltip inside `body`, we directly insert
it inside the `reference` element. This helps us to automatically
hide the tooltip when we hide the `reference` element.
This avoids the bug of tooltip persisting when the message reaction
is removed while the tooltip is active.
To reproduce:
* React 👍 to a message.
* Hover over the reaction.
* Press `+` from keyboard.
You will see reaction tooltip persisting while the reaction is hidden,
also "Add emoji" icon is displayed with tooltip.
Doing the same for elements which are inside a simplebar container
and for which tooltips can span outside the simplebar container,
makes the tooltips not visible or cut at the edges of simplebar
container since simplebar containers have overflow set to `hidden`.
This is something that cannot fixed as per
https://github.com/Grsmto/simplebar/issues/347
So, for simplebar contained elements we insert the tooltip to
`body`.
`reference` element: Element for which tooltip is displayed.
Tippyjs automatically places it to bottom.
NOTE: placement of tooltip is changed from 'bottom' to `auto`.
Custom css was set here to avoid tooltip being partially hidden
on small screens. This change automatically takes care of it
by showing the tooltip on right side of message_reaction on
small screens if it is partially hidden from the left or
vice versa.
Our aim is to use this library to remove use of bootstrap-tooltip
for showing popovers and tooltips. This will remove our
dependency on bootstrap for showing tooltips. Thus, bootstrap
can be upgrade more independently.
