Fixes an issue where images in MD required a relative specifier (e.g.
`./`)

Now, you can use the standard `![](relative/img.png)` syntax in MD files
for images colocated in the same folder: no relative specifier required!

There is no need to update your project; your existing images will still
continue to work. However, you may wish to remove any relative
specifiers from these MD images as they are no longer necessary:

    ```diff
    - ![A cute dog](./dog.jpg)
    + ![A cute dog](dog.jpg)
    <!-- This dog lives in the same folder as my article! -->
    ```

Thanks [@&#8203;martrapp](https://togithub.com/martrapp)! - Due to
regression on mobile WebKit browsers, reverts a change made for
JavaScript animations during view transitions.
