Problem description

I have got an issue with a form builder. My form consists of multiple tabs with where various tabs and/or form elements get shown/hidden depending on live form data. I have noticed, that last tab content gets misplaced depending on form input states.

Even though the original problem I had was on a real project, where we have quite a complex form, I have managed to reproduce it using simplified sample form. I am not sure whether it is Filament bug, Livewire bug or just an user error. I hope you can share your thoughts.

I have created a fresh repository https://github.com/mariusaustr/filamentphp-tabs-bug where you can clone it down, follow steps in readme.md to set the project up, view more unexpected behaviour screenshots & reproduce the bug (?). Since the bug can be reproduced in fresh repository, I think cache or out of date dependencies are out of question.

The Problem:

When you check 2 live() checkboxes in Details tab, the form element from the last tab gets displayed in the bottom of every tab.
When you uncheck those 2 live() checboxes - the last tab form component goes missing

Expected behavior

I would expect the tab content to be properly shown regardless of what the form state is.

Steps to reproduce

git clone git@github.com:mariusaustr/filamentphp-tabs-bug.git
cp .env.example .env
composer install
php artisan key:generate
php artisan migrate --seed
php artisan serve
Navigate to http://localhost:8000/admin (or any other URL if php artisan serve provides different port)
Login using credentials: test@example.com + password (Defined in DatabaseSeeder)
Navigate to Users section & press New User to get redirected to Create User form.
You will see multiple tabs, where form elements are displayed as expected.
In Control Tab check any of Available checkboxes & then check Option 2 of the same category
[BUG] Confirm content from last tab is shown in the bottom of every tab. In the last tab it looks like padding disappears - This should not happen
[BUG] If you uncheck the Option 2 checkbox you have just checked, the content from the last tab disappears completely from all tabs, even the last one - This should not happen either

Form definition

public static function form(Form $form): Form

                'option_1' => false,
                'option_2' => false,
            ];

                        Tab::make('Dummy Tab 4')
                            ->schema([
                                Fieldset::make('Dummy fieldset from last tab')

                                        Forms\Components\Checkbox::make('todo.check'),

                            ]),
                    ]),
            ]);
    }

Is it something I am doing wrong? or is his a bug?
