History Preview - unterminated entity reference stage=Stage

[rafaeldsousa]

The following is triggering a warning when trying to parse a not found file and the error page is loaded instead. This seems to be caused because the returned Link is not parsed.

silverstripe-assets/src/Shortcodes/FileShortcodeProvider.php

Line 102 in ce9464b

$url = $record->Link();

Steps to reproduce

• On a page with an HTML editor field
• Add a link to an existing file
• Save/publish
• Delete file
• Remove the file link from the page
• Save/publish
• Go to the history tab
• Look through your versions and find the one where you had the link to the file that was deleted
• The preview should load with the following error

SilverStripe\View\Parsers\ShortcodeParser::replaceAttributeTagsWithContent(): unterminated entity reference stage=Stage
GET /YOUR_PAGE/?stage=Stage&archiveDate=2021-08-18%2019%3A58%3A11
Line 478 in /Users/.../vendor/silverstripe/framework/src/View/Parsers/ShortcodeParser.php

Note that the error is only reported all the way back up at ShortcodeParser - replaceAttributeTagsWithContent.
