Using nzLeft/nzRight in ng-template not working when used in ngTemplateOutlet

[renzabergos]

Reproduction link

https://stackblitz.com/edit/angular-cdyoxq?file=src%2Fapp%2Fapp.component.ts

Steps to reproduce

• move horizontal scroll from left to right

What is expected?

nzLeft/nzRight directives that are added in <td> inside an ng-template must also reflect when used in the ng-container's *ngTemplateOutlet

What is actually happening?

nzLeft and nzRight are ignored.

Environment	Info

I am using actually using the ng-template from another component, but the issue can be replicated as seen in the link.

there is no method to get component inside the ng-template with ContentChildren with current design of angular now, so we can not support this feature
