[BUG] searching spinner only visible on first open

[saithis]

Describe the bug
When the searching input is true and I open the select dropdown multiple times, then the spinner is only visible the first time.

To Reproduce

1. Go to https://stackblitz.com/edit/github-raw9gr?file=src%2Fapp%2Fexamples%2F01-single-selection-example%2Fsingle-selection-example.component.html
2. Open the single selection dropdown (spinner is visible)
3. Close it
4. Open the single selection dropdown again (spinner is not visible)

Expected behavior
Spinner is visible as long as the searching input is true.

Desktop (please complete the following information):

• OS: Windows 10
• Browser: I tried Firefox 68 and Chrome 74

thanks for reporting. this is due to the animation not being correctly run and can be fixed similar to #133 by removing the animation

@vipulism I can't seem to reproduce the issue with 1.7.6, see https://stackblitz.com/edit/github-yhlsun?file=src/app/examples/01-single-selection-example/single-selection-example.component.html
Please open a new issue with a concise description and the corresponding reproduction steps, so I can have a look at it.
