Objective: be able to select all instances of a font in an SVG and replace it in situ with a different font and have the resulting text maintain the exact same size and relative positioning.
When operating on a single group or object, I can copy it, change the font, then paste size and it more or less accomplishes the above (it does tend to shift the object's position sometimes). However, utilizing the "select all text with this font-family" breaks this. It doesn't copy the size correctly it seems and even working around that, pasting size across multiple objects just doesn't seem to work to maintain the text objects' position relative to each other.
Is there something I'm missing? I'm fairly new to design and inkscape so very likely I'm not doing something considered basic
