Issue in "blockClass" array for "search-result-layout.mobile" block (v3.140.3 or later)

[AlexJSant]

Describe the bug
When you define the blockClass as an array in the search-result-layout.mobile block, VTEX crashes. The link below contains GPT’s explanation of the console error returned in Chrome. I’m not sure why, but this block doesn’t accept multiple classes defined in the "blockClass" prop when passed as an array.

To Reproduce
Steps to reproduce the behavior:

1. Use "search-result-layout.mobile" block (mobile responsive);
2. Add a blockClass prop anywhere, and include more than one class using an array;
3. Example: "blockClass": ["search-content", "search-content-bf"];
4. When you link the app to test, VTEX will throw an error like the one shown in the attached screenshot.

Screenshots

Expected behavior
It should work properly with multiple classes defined in the "blockClass" prop.

Mobile environment:
Tested only on iPhone 11 Pro Max and Chrome DevTools.

Test: Tested adding only one class in the "blockClass" prop, but using the array structure — same error occurs. It should work fine; I’ve already tested it in other blocks and it worked!

Update

In the official documentation, it’s stated that this should be a unique “block ID” for CSS customization, but it still doesn’t make sense for the same prop, used in other components, to behave differently in this one.
Anyway, I’ve tested the same responsive .desktop block, and the same problem occurred.
