124-148: ⚠️ Potential issue | 🟠 Major

Reorder Boolean to last; also set default: undefined for popperStyle.

Two issues with these changes:

1. Ordering (both style and popperStyle): [Boolean, String, Array, Object] activates Vue's Boolean casting rule, so an empty-string value or shorthand attribute usage would be coerced to true (not a valid StyleValue). Move Boolean to the end of the union.

2. Implicit Boolean default on popperStyle (Line 146): unlike style, popperStyle was not given an explicit default: undefined. Because Boolean is now in the type list, Vue treats an absent prop as false rather than undefined, changing the runtime value the component sees when the consumer doesn't pass popperStyle. Setting default: undefined (matching style above and popperContentPropsDefaults.popperStyle at Line 194) restores prior behavior.

🔧 Suggested fix

   style: {
-    type: definePropType<StyleValue>([Boolean, String, Array, Object]),
+    type: definePropType<StyleValue>([String, Array, Object, Boolean]),
     default: undefined,
   },
   ...
   popperStyle: {
-    type: definePropType<StyleValue>([Boolean, String, Array, Object]),
+    type: definePropType<StyleValue>([String, Array, Object, Boolean]),
+    default: undefined,
   },

In `@packages/components/popper/src/content.ts` around lines 124 - 148, The prop
definitions for style and popperStyle are currently ordering Boolean first and
missing an explicit default for popperStyle; update both prop definitions (the
style and popperStyle props in this file where definePropType<StyleValue> is
used) to put Boolean at the end of the type union (e.g., [String, Array, Object,
Boolean]) to avoid Vue's Boolean casting, and add default: undefined to the
popperStyle prop to match style and the existing
popperContentPropsDefaults.popperStyle so the prop value is undefined when not
provided.

Move Boolean to the end of the type unions.

Same Vue Boolean-casting concern as elsewhere in this PR — with Boolean listed before String, any empty-string value or shorthand attribute (<el-scrollbar wrap-style />) on wrapStyle / viewStyle will now be coerced to true, which is not a valid StyleValue and is a behavioral regression relative to before this PR. Reordering Boolean to the tail of the union keeps the original string behavior while still allowing false.

Also worth double-checking: these two props keep default: '' rather than the default: undefined used elsewhere in this PR — that's fine for the casting issue (defaults aren't re-cast), but the ordering still matters for explicit consumer-supplied values.

update the type arrays in the wrapStyle and viewStyle prop definitions (the

at the end of the union (e.g., [String, Object, Array, Boolean] or [Boolean,
String, Array, Object] → move Boolean last) while keeping the existing default:
'' so explicit empty-string behavior is preserved.
