New reason for failing: the button isn't there.

1) FileClipboardCest: See add remove multiple records
 Test  Acceptance/Application/FileList/FileClipboardCest.php:seeAddRemoveMultipleRecords
 [Facebook\WebDriver\Exception\NoSuchElementException] no such element:
 Unable to locate element: {"method":"css selector","selector":"button[data-multi-record-selection-check-action="check-all"]:not(.disabled)"}
  (Session info: chrome-headless-shell=124.0.6367.118)  

This is somehow manually reproducable now.
We have to wait until the content-iframe is fully loaded again. Then we can click on 't3js-multi-record-selection-check-actions-toggle'.

        $I->amGoingTo('add multiple elements to clipboard');
        $I->wait(1);
        $I->click('Clipboard #1 (multi-selection mode)'); // <-- This reloads the whole iframe
        // Wait for iframe loaded and check before going on.
        $I->click('.t3js-multi-record-selection-check-actions-toggle');
        $I->waitForElementVisible('button[data-multi-record-selection-check-action="check-all"]:not(.disabled)');
