I use TexMath plugin to insert math equation in my Chinese document. But the inline equation, which is SVG image, can not keep in the center of the row. I adjust the inline equation position to the center of the row and check the position protect box in the Position and Size dialog. But after I save the document and then open it again, the position of the inline equation recover to the underline of the row. So how to fix this problem?
