Fix for #18262 updated Tundra theme to act like Claro, and
other themes.  A right click followed by an immediate left
click no longer causes the first menu item to fire.
Make dir property case insensitive, fixes #18400.
For lack of a better place, tests added to _BidiSupport/form/test_TimeTextBox.html.
Add aria-autocomplete to ComboBox and FilteringSelect.

Fixes #9089.
Convert test_DateTextBox.html to AMD, refs #18394.
When dateClassObj is not the native javascript Date object,
make sure that this.value is always a dateClassObj.

Fixes #18394, a problem with hebrew calendars.

Unfortunately I don't have an automated test case since it requires code
in dojox/date to test.

Refs #5074 (the support for specifying non-gregorian calendars),
and refs #11251 (which is when the custom `_set()` method was added that calls `compare()`).
Don't expand a tree node when dropping below the node
(i.e. dropping between a collapsed node and its next sibling).

Fixes #17977.

3. Fixed Tree's positioning of icon.
remove "Alternate Themes" tab since its redundant w/the theme menu, fixes #18403
Tree: support numeric id's.
Fixes #18279.
HorizontalRuleLabels: avoid modifying labels property in prototype.

Also did a bunch of test cleanup/reorg, including splitting the unit
tests from test_Slider.html into a dedicated file (Slider.html).

Fixes #18113.
Dialog: for back-compat, make titleBar optional.
Fixes #18253, and dojox/image/Lightbox.
Fix resizing of Dialog with dijitDialogPaneActionBar.

When the dijitDialogPaneActionBar is a sibling of this.containerNode, like in ConfirmDialog,
then resizing the Dialog smaller than its content will keep the OK/Cancel buttons visible,
and add the scrollbar just to this.containerNode.

Fixes #18316.
