\displaystyle command lets the equation in math mode

[i3vi3]

If we write a command like

[latex]\displaystyle \sum_{i=1}^n[/latex]

I think it should displayed in inline mode but the rendering itself is like display mode (e.g. with "i=1" just below \sum.) In fact, this is the usage of \displaystyle and the original KaTeX also behaves like this.

The current \displaystyle in wp-katex seems to be equivalent to adding display="true to [latex], but this is not a standard behavior.

I love this plug-in so much and would be very glad if you could fix this issue.

This is intended behavior, but you can work around this by putting a space before the \displaystyle at the beginning of the equation. For example:

[latex] \displaystyle whatever[/latex]

Thank you very much for your comment. It works as I intended :)
