Fix: Incorrectly hiding the 'Select all X' table link

[dev-idkwhoami]

Description

This PR is related to issue #12781.

The "Select all X" link was hidden by comparing the amount of selected records with the "selectable" records on the page.
But since records stay selected across pages this caused the undesired behavior.

The code change instead checks if the current pages records all are part of the selected records.

Visual changes

Before recording can be found in the issue.

There are a total of 5 selected records matching the pages record count but the link is still shown.
That was previously not possible.

Functional changes

• Code style has been fixed by running the composer cs command.
• Changes have been tested to not break existing functionality.
• Documentation is up-to-date.

Thank you for fixing my bug report.
However, I think it's necessary to add a condition to handle cases where selectCurrentPageOnly is not used.

Here is a video showing the case where selectCurrentPageOnly is not used:

There is another issue.
When switching pages it doesn't refresh so when u go from a page where it should not be visible to a page where it should it stays hidden and the other way around as well.

I've changed it so instead of a random string that refreshes on every request, it will only refresh when the page is changed

Can you test that it still works and let me know please?

I pulled the changes you made couldn't find any change in behavior 👍
