Since one of the more recent updates, all text in imported PDFs is converted to Text boxes rather than artistic text, irrespective of the options chosen when importing the file (i.e. 'Group lines of text into text frames' checkbox deselected). While this may be a good choice for many texts, it completely screws up the workflow for (scientific) illustrations with text labels coming from other applications. Below I have illustrated the consequences of a font change by 2.8pt if everything is imported as box vs artistic text.
Please fix soon, or give option to prefer artistic text over text frames for single line texts.
