## TLDR
* Improve performance: lazy creating the tippy instances.
* Transparently support all "tooltip" elements, no need to call
`initTooltip` again and again.
* Fix a temporary tooltip re-entrance bug, which causes showing temp
content forever.
* Upgrade vue3-calendar-heatmap to 2.0.2 with lazy tippy init
(initHeatmap time decreases from 100ms to 50ms)
## Details
### The performance
Creating a lot of tippy tooltip instances is expensive. This PR doesn't
create all tippy tooltip instances, instead, it only adds "mouseover"
event listener to necessary elements, and then switches to the tippy
tooltip
### The general approach for all tooltips
Before, dynamically generated tooltips need to be called with
`initTooltip`.
After, use MutationObserver to:
* Attach the event listeners to newly created tooltip elements, work for
Vue (easier than before)
* Catch changed attributes and update the tooltip content (better than
before)
It does help a lot, eg:
