Clicking a decade in the Datepicker's decades view could open the wrong years. The click handler only changed the view when a date was selected, and then shifted the current view by clickedDecade - selectedYear. With no selected date the view never moved (click 1990, get 2020 - 2031, or 1920 - 1931 after paging back), and after paging back with the arrow you ended up a century off (click 1990, get 1890 - 1901).

The handler now sets the view date to the date it already computes for the clicked decade, like the years view does. I added two tests (paging back, and no selected date) and a patch changeset. No API or theme changes.

Fixes #1516

After paging back once and clicking 1990 (Default story):

The video shows the Default Datepicker story: open the picker, go to the decades view, page back once, click 1990, and the years view shows 1990 - 2001.

Summary by CodeRabbit

  • Bug Fixes
    • Fixed the Datepicker’s decades view so selecting a decade after paging backward displays the correct year range, including when no date is selected.

Clicking a decade only moved the view when a date was selected, and then
shifted the current view by the distance to the selected year, so the
years view could open on the wrong decade. Set the view date to the date
computed for the clicked decade, as the years view does.

Walkthrough

The Datepicker now sets its view date to the clicked decade’s precomputed date. Tests cover selection after paging backward and selection when no date is selected. A patch changeset records the fix.

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: sutusebastian

Merge Risk: Low · up to ecf51

The fix addresses ordinary decade selection, but negative-year dates can still open the wrong decade. This narrow edge case warrants a small correction or explicit follow-up; otherwise the change has low merge risk.

Nitpick Assert the rendered years after the decade click.

112-112: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Assert the rendered years after the decade click.

After the click on 1990, the first new test checks only the title. The year buttons come from a separate computation in Years.tsx. A later change that renders the year buttons from a different anchor than the title would still pass. Add an assertion on the year grid so the test covers the years users can select.

🧪 Suggested test assertion
     await userEvent.click(screen.getByText("1990"));
     expect(titleButton.textContent).toBe("1990 - 2001");
+    expect(screen.getByText("2001")).toBeDefined();
   });

Normalize the year remainder so negative years select the clicked decade.

For negative years, JavaScript's % returns a negative remainder. The target year then falls in the preceding decade. For a view year of -1 and the -100 button, the target year is -101. The years view then shows -110 - -99 instead of the decade that was clicked, -100 - -89. Use a non-negative remainder.

Suggested fix
-        newDate.setFullYear(year + (viewDate.getFullYear() % 10));
+        newDate.setFullYear(year + ((viewDate.getFullYear() % 10) + 10) % 10);
