Overview of the issue

If you are using the Language Switcher Gutenberg block and its Dropdown click option, you will notice that when clicking outside the dropdown area, it won’t be close as expected.

Workaround

Please, make sure of having a full site backup of your site before proceeding.

• Open …/wp-content/plugins/sitepress-multilingual-cms/classes/block-editor/Blocks/LanguageSwitcher/Render.php file.
• Look for line 123.
• Replace:

  				if ( $dpFirstItem ) {
  					$dpFirstItem->setAttribute(
  						'onclick',
  						"(()=>{const ariaExpanded = this.children[0].getAttribute('aria-expanded');
  					this.children[0].setAttribute('aria-expanded', ariaExpanded === 'true' ? 'false' : 'true');})(this);"
  					);
  				}
  

• With:

  if ($dpFirstItem) {
      $dpFirstItem->setAttribute(
          'onclick',
          "(()=>{
              const ariaExpanded = this.children[0].getAttribute('aria-expanded');
              this.children[0].setAttribute('aria-expanded', ariaExpanded === 'true' ? 'false' : 'true');
              
              if (ariaExpanded !== 'true') {
                  const expandedItem = this;
                  const closeExpandedItem = (event) => {
                      if (!expandedItem.contains(event.target)) {
                          expandedItem.children[0].setAttribute('aria-expanded', 'false');
                          document.removeEventListener('click', closeExpandedItem);
                      }
                  };
                  document.addEventListener('click', closeExpandedItem);
              }
          })(this);"
      );
  }
