Drupal 8.x

I have a problem with an Ajax view. I have a SearchAPI Block and whenever I change the filters the block reloads and the page scroll jumps randomly. This problem does only appear when the page is short enough. I have another Search API Block at a different page of the same Drupal installation but with more other blocks under that than just the footer.

I do not think that it has anything to do with the settings of my SearchAPI or even the Infinity Scroll Module. I think it happens when the page is not really long and Ajax adds some new DOM Elements.

In my opinion, permissions are currently a weakspot in Drupal, especially for community-based websites, where many permissions would depend on user group membership (such as permission to edit content owned by a member of the same user group) and many finer permissions are needed, such as being able to add content to fields, but not edit.

Are they going to evolve? What are the plans?

Strange that require and update just started posing difficulty. After hours of attempt update now works but requires returns out of memory or allocated memory. I have set the memoy_limit to -1 and have updated composer to the 1.10.1, D8 core to 8.8.5 using the core-recommend template as well as 2 out of date modules. But I'm unable to download new modules (some don't permit using tar).

My local development is on WAMP (PHP 7.3.7) windows 10, intel i7, 16Gb RAM.

Any idea?

Using Drupal 8, and customizing a subtheme based on Bootstrap 3.

When I click the mobile menu button (button element with the "navbar-toggle" class), the menu appears, but does it a bit too slowly; I need to reduce that time (or bring it to zero, need to see how it goes, to decide), but am unable to do so.

I've seen that when the button is clicked, the div of the menu

<div id="navbar-collapse" class="navbar-collapse collapse in" aria-expanded="true" style="">
