Description

#### Reproduction

Use StackBlitz to reproduce your issue: https://stackblitz.com/edit/angular-7-master-svg1

Steps to reproduce:
1. Setup shared components for svg icon, sidebar content and page content alongside the ability to toggle mat-sidenav.
2. Toggle Sidenav and see all svg icons on the page get disappeared on sidenav close and re-appear on sidenav open.


#### Expected Behavior

No svg icon should disappear from the page.

#### Actual Behavior

Toggling Sidenav makes all svg icons on the page disappear on sidenav close and re-appear on sidenav open. Moreover, if you inspect the html output of page and components, you will see that svg icons are still present there, with no change in attributes, html, etc. Furthermore, this bug happens with some icons only (not sure what is the differentiator as there's dozens of icons in our locally under-development app that exhibit this weird bug, but there are also some that don't), for example, svg icon in this stackblitz works correctly. https://stackblitz.com/edit/angular-7-master-svg2

Commencez par les deux reproductions StackBlitz liées, angular-7-master-svg1 et angular-7-master-svg2, et comparez le comportement de basculement de mat-sidenav avec les icônes SVG.
