Previously, when using shortcuts to increase or decrease the font size of the selected text, the size would jump to 0. This behavior occurred because, if the text did not yet have a font tag, the initial font size was evaluated as 0. This commit ensures that the text tool's default font size is used when no font tag is present. This prevents the font size from jumping to 0 the first time the shortcuts are used.
