Expandable table's animation is lagging

#### What is the expected behavior?

Animation works well without any lagging when I open the (expandable) table's row.

#### What is the current behavior?

When I try to open the row clicking on it, it is not animating, but it is lagging.
(When I close the row clicking on it again, animation works very well.)

#### What are the steps to reproduce?

https://stackblitz.com/edit/angular-sbj26m

#### Which versions of Angular, Material, OS, TypeScript, browsers are affected?

"@angular/material": "7.3.4",
"@angular/cdk": "7.3.4",
"@angular/core": "7.2.9",

- Chrome, Opera, Firefox latest
- Edge, Internet Explorer latest (I cannot open the expandable row at all.)

Comienza con la reproducción enlazada de StackBlitz y reproduce el comportamiento de la tabla expandible utilizando las versiones indicadas de Angular, Material, CDK y los navegadores. Compara la apertura y el cierre de la fila, incluido el fallo notificado en Edge e Internet Explorer. Se considera completado cuando la fila se abre y se cierra con una animación fluida sin el retraso notificado.
