Loading spinner not visualized correctly in ie11

[dollaniErlind]

While I was testing my angular web application in internet explorer 11, I noticed that loading spinner is not visualized correctly. In all other browsers it is ok. Here is my code:
<ng4-loading-spinner [timeout]="10000"> </ng4-loading-spinner>

Attached below is the loading spinner.

Dependencies
angular: 6.0.3,
bootstrap: 4.0.0
ng4-loading-spinner: 1.2.3

Solved this problem by adding this line of code (ie11 target only style):
_:-ms-fullscreen, :root .spinner { background: rgba(0, 0, 0, 0.99); }
