Expected Editor Behavior

Interacting with Math Nodes

This section describes the expected behavior of math nodes created with prosemirror-math. Since ProseMirror relies on contenteditable, which behaves differently in each browser, you might experience buggy behavior in your browser of choice. If you notice something unusual, please file a bug report!
