Multiple Pagination(Mat-table & Pagination): Multiple pagination in same component with different data source not working

#### Description
I tried to put two tables in one component with different data sources which worked well with the data rending part. However, the paginator didn't work on the second table.

#### Reproduction
Please use StackBlitz to check the issue:
**StackBlitz Project Editor link**: https://stackblitz.com/edit/angular-brxwzo
**StackBlitz Output link**: https://angular-brxwzo.stackblitz.io

#### Steps to reproduce:
1. Create two table
2. Create two data sources with different numbers of elements into it.
3. Bind the data source with the respective data source for eg.
` displayedColumns: string[] = ['position', 'name', 'weight', 'symbol'];
dataSource = new MatTableDataSource(ELEMENT_DATA);
dataSource1 = new MatTableDataSource(myData);
`
**Table 1**
`
`
**Table 2**
` `
4. Create the paginator for the following datasouces:
` @ViewChild(MatPaginator, {static: true}) paginator: MatPaginator;
@ViewChild(MatPaginator, {static: true}) paginator2: MatPaginator;`
5. Only the first paginator will work in the output.

#### Expected Behavior

Like the first table pagination, the second table pagination should also work independently to the first as the data sources are different, the paginator pointing instance is different.

#### Actual Behavior

Only the first table pagination is working rest of all other table pagination are begin ignored.

#### Environment

- Angular: 9.0.5
- CDK/Material: 9.2.4
- Browser(s): Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): Ubuntu 20.01

Apri il progetto StackBlitz collegato e riproduci il problema utilizzando le due istanze di MatTableDataSource e MatPaginator descritte nei passaggi. Traccia i due binding dei paginator e verifica che ogni tabella pagini i propri dati in modo indipendente; il lavoro è completato quando il secondo paginator funziona senza influire sul primo.
