If TCEFORM.pages.categories.config.treeConfig.rootUid is set non-admin users only get shown the (new) root category but no child nodes.

This does work for fields but not in flexforms. I get the same issue.
If you set following code as an example for tt_address plugin, only the category with uid 78 but not the child notes are displayed (for admins this works):
TCEFORM.tt_content.pi_flexform.tt_address_pi1.sDEF.groupSelection.config.treeConfig.rootUid = 78

Testet with TYPO3 7.6.21 and tt_address 3.2.2

I can confirm it with another category field. It has nothing to do with tt_address directly...

The tree items are collected in DatabaseTreeDataProvider.php => loadTreeData()

        $this->loadTreeData();
        $this->emitPostProcessTreeDataSignal();

and then secured via SignalSlot in CategoryPermissionsAspect.php => lookUpCategoryMountPointInTreeNodes(), eg. checked if they match the collection of categories allowed through usergroups.

The problem is, that their parents are not checked, eg. if one of the parents categories is allowed through usergroups. For Admins that check is not done, see

    public function addUserPermissionsToCategoryTreeData(DatabaseTreeDataProvider $dataProvider, $treeData)
    {
        if (!$this->backendUserAuthentication->isAdmin() && $dataProvider->getTableName() === $this->categoryTableName) {

It has nothing to do with flexform field or not and looks broken in general... or a missing Feature? ;-)

Workaround: Allow every category you want so see under rootUid in your usergroup
