This issue is similar to #14767 in 1.7.4.
In labelling, the size of the font can be selected in two places, in the "label settings" tab but also in the dialog that opens when choosing the type of the font. In the latter dialog choosing the size of the font has not effects. Also, when choosing a different font from the previous selected, the font size always reverts to 8 pt.
