Important: The job contact block shows its own icons

Description

The contact block of the job detail view asked the icon registry for the identifiers phone and mail. Neither TYPO3 v13 nor v14 registers them, and no academic extension did, so a stock installation showed the "icon not found" drawing of TYPO3 in front of the contact phone number and the contact e-mail address. A real icon only appeared where the site package happened to register phone and mail itself.

The block now renders two icons the extension registers, tx-academicjobs-info-contact-phone and tx-academicjobs-info-contact-email. They are rendered like the property icons of the same view, as the shared Font Awesome Free glyphs of academic_base, inlined and drawn in currentColor:

before: <span class="t3js-icon icon icon-size-small icon-state-default icon-default-not-found"
              data-identifier="default-not-found" aria-hidden="true">
            <span class="icon-markup"><svg …>…</svg></span>
        </span>
after:  <span class="t3js-icon icon icon-size-small icon-state-default icon-tx-academicjobs-info-contact-phone"
              data-identifier="tx-academicjobs-info-contact-phone" aria-hidden="true">
            <span class="icon-markup"><svg … width="1em" height="1em" fill="currentColor">…</svg></span>
        </span>

The e-mail row is the same with tx-academicjobs-info-contact-email. The identifiers are those of Breaking: The job icons are renamed and moved to the frontend icons.

Impact

A stock installation needs nothing, the block shows a phone and an e-mail icon where it showed the placeholder. They take the colour of the surrounding text and are as large as its font.

A site package that registered phone or mail to give this block an icon now sees the shipped icons in the block. Its registrations stay harmless and keep serving its own templates. To keep its own drawing in the block, it registers the file under the identifier the block renders, in the Configuration/FrontendIcons.php of the site package. That file belongs to the frontend icon registry of academic_base, which the block renders its icons from, see Breaking: The job icons are renamed and moved to the frontend icons. The site package requires fgtclb/academic-jobs and lists academic_jobs under depends in its ext_emconf.php, so it loads later and its registration wins:

EXT:my_sitepackage/Configuration/FrontendIcons.php

use TYPO3\CMS\Core\Imaging\IconProvider\SvgIconProvider;

return [
    'tx-academicjobs-info-contact-phone' => [
        'provider' => SvgIconProvider::class,
        'source' => 'EXT:my_sitepackage/Resources/Public/Icons/Phone.svg',
    ],
    'tx-academicjobs-info-contact-email' => [
        'provider' => SvgIconProvider::class,
        'source' => 'EXT:my_sitepackage/Resources/Public/Icons/Mail.svg',
    ],
];

SvgIconProvider renders the file as an image of 16 by 16 pixels. A file drawn in currentColor and registered with \FGTCLB\AcademicBase\Imaging\IconProvider\CurrentColorSvgIconProvider is inlined like the shipped icons.

A stylesheet that selects .icon-phone or .icon-mail has to select the new identifier classes instead.

An installation that overrides Resources/Private/Partials/Job/Contact.html in its own site package keeps its own output and its own identifiers.
