The Reference Style sets an invisible vertical (typographical) grid, using the line distance specified in the style. All paragraphs that have Page line-spacing activated will use that line distance, aligning the bottom of a text line to the next grid line, regardless of font size or presence of graphics.

Open the Styles window (Command+TF11), click the Paragraph Style you want to exempt, right-click that style, choose Modify. In the dialogue box, click the Indents & Spacing tab.
