Drupal 8.x

I am working on a theme for Drupal 8/9 that is based upon Bootstrap 5. I use sass to generate style.css from .scss-sources.

I have a content type named "Polaroid". It has fixed width an height (300 by 350 px). I want to show this content stacked sideways. The visual effect I am looking for is similar to what you could get with the Drupal 7 project DAN Polaroid (screenshot below):

I created a Views page with the following path to replace the default "Profile" module page for my "projects" profile type:

    /user/ID/project/list

You have to click on "Projet" to display the profiles.

With the default page I have this display :

After clearing all caches and when browsing pages via admin interface (logged in as administrator) a lot of entries of a System type are created in DBLOG. The pages are being displayed correctly.

Here is the scenario:

1. All caches cleared

2. Visit a single page while being logged in as administrator (browse via admin interface)

3. Check DBLOG

After viewing just one page 48 entries were created in DBLOG

11 x The "views_block" was not found
All 11 entries have the same details

I created a comment type for the profile entity. When I create a profile, I can set comments as open, closed, or hidden.

I have created a view profile block, and I want to display in front of each profile whether the comments are open or closed.

How can I achieve this ?

I want to add a local task (tab) on the user profile page.  This will be /user/<uid>/nodes (very similar to existing tab with url = /user/<uid>/activity).

The differences are:

1. the activity tab shows the user activity in both nodes and comments listed in time............where as I want node tab to show only nodes submitted by the user.

2. If the user is reading his/her own nodes listing, all nodes (published and unpublished) should be listed. If the user is reading list for any other user, only published nodes will be listed.

My questions:

Will this module: https://www.drupal.org/project/polyfill support Promises or async/await in IE. I placed the dependencies in my library but nothing seemed to happen. Has anyone used this before?
