Although it seems that some different purposes are mixed in this PR,
however, they are all related, and can be tested together, so I put them
together to save everyone's time.
Diff: `+79 โ84`, everything becomes much better.
### Improve the dropdown settings.
Move all fomantic-init related code into our `fomantic.js`
Fine-tune some dropdown global settings, see the comments.
Also help to fix the first problem in #23625 , cc: @yp05327
The "language" menu has been simplified, and it works with small-height
window better.
### Use SVG instead of `<i class="delete icon">`
It's also done by `$.fn.dropdown.settings.templates.label` , cc:
@silverwind
### Remove incorrect `tabable` CSS class
It doesn't have CSS styles, and it was only in Vue. So it's totally
unnecessary, remove it by the way.
### Improve the Repo Topic Edit form
* Simplify the code
* Add a "Cancel" button
* Align elements

Follow:
* #23574
* Remove all ".tooltip[data-content=...]"
Major changes:
* Remove "tooltip" class, use "[data-tooltip-content=...]" instead of
".tooltip[data-content=...]"
* Remove legacy `data-position`, it's dead code since last Fomantic
Tooltip -> Tippy Tooltip refactoring
* Rename reaction attribute from `data-content` to
`data-reaction-content`
* Add comments for some `data-content`: `{{/* used by the form */}}`
* Remove empty "ui" class
* Use "text color" for SVG icons (a few)
## 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:
1a4efa0ee9/web_src/js/components/PullRequestMergeForm.vue (L33-L36)
### Temporary tooltip re-entrance bug
To reproduce, on try.gitea.io, click the "copy clone url" quickly, then
the tooltip will be "Copied!" forever.
After this PR, with the help of `attachTippyTooltip`, the tooltip
content could be reset to the default correctly.
### Other changes
* `data-tooltip-content` is preferred from now on, the old
`data-content` may cause conflicts with other modules.
* `data-placement` was only used for tooltip, so it's renamed to
`data-tooltip-placement`, and removed from `createTippy`.
Follow #23394
There were many bad smells in old code. This PR only moves the code into
Vue SFC, doesn't touch the unrelated logic.
update: after
5f23218c85
, there should be no usage of the vue-rumtime-compiler anymore
(hopefully), so I think this PR could close#19851
