Nested and hidden/disabled mask content elements not visible in backend preview

[Wintermilch]

Using TYPO3 12.4.10 and Mask 8.3.8

I'm using custom templates for the backend preview of my mask elements.
In these previews I'm also showing the nested/child elements.

Now if any element has nested elements, the preview works fine.
Example:

But if I hide a nested record, it'll disappear but it shows up in the edit view. (it is not deleted):

I've searched through the code and found why this does not work.
Inside the InlineHelper class I've found this line which checks if we are in work space preview mode:

mask/Classes/Helper/InlineHelper.php

Line 264 in ead5ddb

$inWorkspacePreviewMode = $workspaceId > 0;

But in the page module the workspace id is 0. So changing the condition to $workSpaceId >= 0; will then remove the querybuilder restrictions some lines later.

Then in this line the condition for the disabled field had to be removed in order not continue the loop.

mask/Classes/Helper/InlineHelper.php

Line 309 in ead5ddb

if ($element === null || ($element[$GLOBALS['TCA'][$childTable]['ctrl']['enablecolumns']['disabled']] ?? false)) {

With these 2 adjustments, my preview works fine again:

NOTE: This does not happen if nested element is from tt_content table.

@Wintermilch I had the false assumption back then that hidden records should not be displayed in backend previews. This is now fixed.

NOTE: This does not happen if nested element is from tt_content table.

Yes! This is because they are handled differentely (better) than Inline fields. This should ideally be unified so everything behaves identically. This is a very legacy part of the Mask Code. However, my focus is currently on Content Blocks and I won't be doing larger refactorings of the Mask Code for the forseeable future.
