Range Slider Thumps collapsing

[shaunlab]

Description

The Range Slider has a left and a right thumb that appear during interaction to both ease the end user navigation and also display the current slider value. These need to stay expanded whenever the user interacts with the control but the range thumbs currently hide after several seconds in Internet Explorer 11.
This is a duplicate of #463 although the issue still seems to exist in IE 11.

• igniteui-angular version: 6.1.5
• browser: Internet Explorer 11

Steps to reproduce

1. Adjust slider min/max values in IE 11.

Result

the label disappears while still dragging the dot

Expected result

Thumbs to stay visible during the whole interaction

@shaunlab This could be a side effect of the web animations polyfill, since the standard animations are not supported in IE11. We will investigate!

Thanks @kdinev - hopefully there will be a fix for this implemented soon.
To add to this:
This also seems to occur in Chrome & Native browser on Android
