Hide validation icons from multiple selects

Implementation provided in #33411 does not take into account that some
Operating Systems may display a vertical scrollbar in the multiple
select field

This implementation will hide the validation icons from multiple select
fields, just like Bootstrap 4 does.

Fix: #33591

fix: make EventHandler better handle mouseenter/mouseleave events (#33310)

* fix: make EventHandler better handle mouseenter/mouseleave events

* refactor: simplify custom events regex and move it to a variable

Update devDependencies (#33590)

* @babel/core        ^7.13.14  →  ^7.13.15
* @babel/preset-env  ^7.13.12  →  ^7.13.15
* eslint              ^7.23.0  →   ^7.24.0
* postcss              ^8.2.9  →   ^8.2.10
* rollup              ^2.44.0  →   ^2.45.1
* vnu-jar              21.2.5  →    21.4.9

refactor: make static `selectMenuItem` method private (#33589)

Remove element event listeners through base component (#33429)

After some research, I found out that EventHandler saves all the custom events per element using namespace, and is capable of removing handlers using only the element and its namespace (`DATA_KEY`).

So, probably is better to utilize the base-component to do the same job.

Update tests to check for `noop` to be removed

Dropdown — Don't use event delegation

Use cached `noop` function everywhere

Decouple Modal's scrollbar functionality (#33245)

Add color-scheme mixin

docs: update clipboard.js to v2.0.8 (#33583)

footer: fix `rel=noopener` attribute (#33571)

There's no need to use `rel=noopener` without `target=_blank`, but otherwise, it should be used since it's a potential security issue.

Remove unnecessary `data-bs-backdrop="static"` (#33578)

Since the value for the `backdrop` option is available in the configuration object.

Fix wrong carousel transformation, direction to order (#33499)

Improve responsiveness of Features examples

Fixed wrong method name _getInstance

There is no _getInstance method, but there is a getInstance method

Revert "Update look and feel of examples and copy buttons"

This reverts commit cdf56e0eefd797d4b0f26021d24958fc315a5f2c.
