Describe the bug
For example, in my Markdown document, there is a line of code like this:
<img src="proxy.php?url=https%3A%2F%2Fgithub.com.%2F.%2Fimages%2Fplaceholder_batch_preview.jpg" width="40%" alt="batch_preview" />
However, when viewed in the Chrome browser, the image is displayed at 100% width, which makes it look very uncoordinated.

Using Chrome DevTools, I found the following injected CSS code:

.mdr-body[data-v-96c33c2d] .mdr-content embed,
.mdr-body[data-v-96c33c2d] .mdr-content iframe,
.mdr-body[data-v-96c33c2d] .mdr-content img:not(.equation),
.mdr-body[data-v-96c33c2d] .mdr-content video {
    max-width: 100% !important;
    margin: 0px;
}
