schizophrenicmaniac opened a new pull request, #44963:
URL: https://github.com/apache/superset/pull/44963

   ### SUMMARY
   The Run button in Explore is disabled while any control has validation 
errors, and it turns into a Stop button while the chart is loading. The 
Ctrl/Cmd+Enter shortcut called `onQuery()` directly and skipped both checks, so 
it could trigger a query (and push a history entry) with an invalid control 
panel, or fire a second query while one was still running.
   
   `handleKeydown` now applies the same rules as the button. It returns without 
querying if any control has non-empty `validationErrors` (the same condition 
behind `errorMessage`), or if `chart.chartStatus` is `loading`. I check the 
controls directly rather than reading `errorMessage`, because that memo is 
defined further down the component, after the keydown handler and its effect.
   
   I added RTL tests to ExploreViewContainer.test.tsx: Ctrl+Enter and Cmd+Enter 
still run the query when controls are valid, and the shortcut does nothing when 
a control has validation errors or while the chart is loading.
   
   ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF
   No visual change. The only difference is that the keyboard shortcut no 
longer runs a query in these cases. A before/after recording is still to be 
added.
   
   ### TESTING INSTRUCTIONS
   1. Open a chart in Explore and clear a required control (e.g. remove all 
metrics) so the Run/Update chart button is disabled with an error tooltip.
   2. Click somewhere on the page outside an input and press Ctrl+Enter 
(Cmd+Enter on macOS). No query should run and the URL/history shouldn't change.
   3. Fix the control and press Ctrl/Cmd+Enter again. The query should run.
   4. Start a slow query and press Ctrl/Cmd+Enter while it's loading. No second 
query should start.
   5. `npm run test -- 
src/explore/components/ExploreViewContainer/ExploreViewContainer.test.tsx`
