Hello Rajendra and welcome to E-Learning Heroes :)

Thanks for contacting us to share what you are seeing with your wipe animation.

HTML5 support in Internet Explorer and classic versions of Microsoft Edge lags behind other major browsers. For example, these Microsoft browsers don’t support "masking" animations in HTML5 content. You can read additional details here.

As a coda to Leslie's comment above, it has been well-known in professional Web design that Internet Explorer is problematic in rendering content, and it has been this was for a very very long time. In fact, IE6 was so bad that Web designers would flat-out advise their clients that their work would not be edited to accommodate IE6, no matter what. End users had to upgrade beyond IE6 - too bad!

The tradition continues to this day. Recent IE and Edge simply do not behave by the same set of rules as every other major browser. So don't take Leslie's comment as a knock against SL. IE has been a pain in the a** for many years.
