TYPO3 Core

Hi,

the linkhandler popup (link browser) forgets all settings after switching tabs.
On link-browser-before-error.PNG you will see that link browser is restricted to fewer options.
After switching between tabs (News and Page) multiple times the browser loses all settings. Take a look at link-browser-after-error.PNG and the changed url. As you can see all settings got lost.

1.Reproducible with the lastest introduction package (8.7.8) and the carousel FCE.

2.Modify bootstrap_package\Configuration\TCA\tx_bootstrappackage_carousel_item.php by adding some blindLink stuff to the link field:

'blindLinkOptions' => 'file, mail, spec, url',
'blindLinkFields' => 'class, params, target, title'

3.Add new tab to link browser by modifing bootstrap_package/Configuration/PageTS/TCEMAIN.txt

TCEMAIN.linkHandler.tx_news {
    handler = TYPO3\CMS\Recordlist\LinkHandler\RecordLinkHandler
    label = News
    configuration {
        table = tx_news_domain_model_news
    }
    scanBefore = page
}

4. Switch between tabs (News and Page) multiple times until the bug appears.
