Side nav overlaps the content in IE1 1

[olesea]

Hello, 

I have a problem in IE with the same described here :

[DW-370] Side nav overlaps the breadcrumb - Alfresco JIRA 

I looked in the developer tools. It seems that the first time when the page is loading the margin of the content is 

Not the margin of the sidenav. It is interesting if you toogle the sidenav then it is fixed. It is very strange since the class of opened for mat-sidenav is there.

Does anyone know how to fix this? I tried to add a width for sidenav but it did not solved it:

Thank you
