Code optimization for W3C HTML Validator

Hi,

I’m currently trying to fix some remaining HTML issues in a project. There’s a tiny HTML-“bug” in your plugin.

The following line is in floating-switcher.php:

echo '<div class="' . esc_attr( $class ) . '" ' . $title . ' role="button" tabindex="0" aria-expanded="false"' . 'aria-label="' .  esc_attr( $current_language_label ) . '" aria-controls="' . esc_attr( $dropdown_id ) . '" ' . $no_translation . '>';

The output looks like this:

<div class="trp-language-item trp-language-item__current" title="Deutsch" role="button" tabindex="0" aria-expanded="false"aria-label="Change language" aria-controls="trp-switcher-dropdown-list" data-no-translation><img src="flagurl" class="trp-flag-image" alt="" role="presentation" loading="lazy" decoding="async" width="18" height="14" /><span class="trp-language-item-name">Deutsch</span></div>

There’s a missing space between aria-expanded and aria-label. It would look better like this:

echo '<div class="' . esc_attr( $class ) . '" ' . $title . ' role="button" tabindex="0" aria-expanded="false" aria-label="' .  esc_attr( $current_language_label ) . '" aria-controls="' . esc_attr( $dropdown_id ) . '" ' . $no_translation . '>';

Second case in the same file:

echo '<a href="' . $url . '" class="' . esc_attr( $class ) . '" ' . $title . $no_translation . '>';

A space should be added here, e.g. like this:

echo '<a href="' . $url . '" class="' . esc_attr( $class ) . '" ' . $title . ' ' . $no_translation . '>';

It would be great if you could take this into account in future updates. This would ultimately also help screen readers with less tolerant errors.
