Memory issues after using a small svga

[errorman]

We have a svga-file at work, I check the svga with svga-online-player and it’s memory is very fine(0.7M), but when I use it at my project, the page memory is increased by dozens of MB, I want to know what went wrong.

Here are the information about this svga-file from svga-online-player

{
  "version": "2.0",
  "FPS": 30,
  "frames": 90,
  "videoSize": {
    "width": 1500,
    "height": 1624
  }

This is the svga-file

Can you provide a demo? And how much memory used?

Sorry, I have been busy some time ago.
Here is the demo link, https://www.wulihub.com.cn/go/WwbNyq/index.html. Open the Developer tools --> More tools --> Performance monitor to view the JS heap.

The page memory is increased by dozens of MB, but I check the svga with svga-online-player and it’s memory is very fine(0.7M) .

So I want to know what went wrong.
Thanks again, Happy New Year.
