'Angular 13 Strange blank line at the end of the page

I use the NGX-ADMIN template which runs on Angular 12. Following an update to Angular 13 (and only a change in the versions of Angular), I encounter this problem, and I have no idea how to identify this type of problem. Would you have an idea, or do you know how to identify this type of problem, the origin?

I confirm once again that it is indeed the modification of the versions of angular from 12 to 13 which generated this problem.

Same problem with Angular : 14.0.0-next.5

Link of the issue : https://github.com/akveo/ngx-admin/issues/5919

    "@angular/animations": "^13.2.5",
    "@angular/cdk": "^13.2.5",
    "@angular/common": "^13.2.5",
    "@angular/compiler": "^13.2.5",
    "@angular/core": "^13.2.5",
    "@angular/forms": "^13.2.5",
    "@angular/material": "^13.2.5",
    "@angular/platform-browser": "^13.2.5",
    "@angular/platform-browser-dynamic": "^13.2.5",
    "@angular/router": "^13.2.5",

After some research the problem seems to appears from there :

<div class="cdk-describedby-message-container cdk-visually-hidden" style="visibility: hidden;"><div id="cdk-describedby-message-1">Sort</div></div>

After manually deleting this, problem is solved. But now how cna i do in order that does not appear

white line at the end of the page

problem here
