Math operators split picture to more lines

Hello, I would like to know whether following behaviour is a bug or feature, alternatively if there is a way how to disable it. When I write a random long text in Online LaTeX Equation Editor (for example content if this message), it generates a wide picture containing whole sentence in one line (desired behaviour). However, as soon as I use a mathematical operator (e.g. +,-,*), the picture is splited at some points (seems like after 600 pixels).

My goal is to create an HTML document containing equations created using this editor. However, it looks really strange when equations are splited to new lines (see attached HTML file). Thank you!

Hi, this is a feature of our current rendering engine. For very long equations we're actually wrapping the equation to what we estimate is the page boundary.

So there is no way how to avoid it?
