Fixes#9058 - the filtering so far is a bit aggressive, but I tune it up in next PR(s).
[Screencast from 2024-03-13 15-20-17.webm](https://github.com/enso-org/enso/assets/3919101/112ce65a-a8c6-4818-b8b8-9f493caf9c81)
Added new special `WidgetEditHandler,` allowing handling "multi-widget" interactions needed for drop down filtering.
# Important Notes
* Now when clicking on argument name, the edit is accepted (as normal "outside" click), and then the dropdown is opened again (due to handling click event). I didn't figure out how to handle this case properly, left something least confusing.
- Improved performance by batching simulatenous node edits, including metadata updates when dragging many selected nodes together.
- Updated Vue to new version, allowing us to use `defineModel`.
- Fixed#9161
- Unified all handling of auto-blur by making `useAutoBlur` cheap to register - all logic goes through a single window event handler.
- Combined all `ResizeObserver`s into one.
- Fixed the behaviour of repeated toast messages. Now only the latest compilation status is visible at any given time, and the errors disappear once compilation passes.
- Actually fixed broken interaction of node and visualization widths. There no longer is a style feedback loop and the visible node backdrop width no longer jumps or randomly fails to update.
Closes#8932
Now we use a bit more robust mechanism for passing dynamic configuration down the widget tree inside dropdowns, no longer relying on the `label`s used for dropdown items.
Curiously, we still need to use a hotfix implemented earlier, as we won’t have info about the currently selected item otherwise. Highlight for the currently selected item is not crucial as proper dynamic config, so we can leave with the current solution in the meantime.
No visual changes to the IDE, apart from fixed highlight for currently selected item.
# Important Notes
Target branch: #8950, for easier testing.
Closes#8823https://github.com/enso-org/enso/assets/6566674/966576ec-6507-401c-98d3-bd71c2ffc6b2
Adds a basic text widget for text literals.
### Important Notes
Several known restrictions:
- Separators would always be replaced with single quotation marks. All types of separators in Enso are supported though, and they would be correctly escaped if needed.
- Logic for widget selection probably needs refinement (works for text literals and `Text` types, but does not work for `Text | Integer`, for example)
- **(!)** There is a very annoying issue when the input field suddenly loses focus, closing the editing mode and discarding any changes. Debugging shows that it happens when we receive an engine update (and probably recreate the node component/widget tree (???)). It requires a separate investigation.
Part of #8518Closes#8822
The drop downs were missing, because WidgetFunction had a higher score than them and took precedence. The fix was to adjust scores, so drop down is before both argument name and function. Generally, any widget expecting to "overlap" existing code (and possibly further widgets) should go before WidgetFunction.
# Important Notes
* Extended mockExpressionUpdate to accept a subexpression of a node. Also, I removed it from GraphDb - I want this function to have as little impact on app code as possible.
