[REG 4.3 -> 4.4] float type is not highlighted in .c and .h files

after update of QtCreator up to 4.4.0 (suggested by update check of maintenance tool) float type in .c and .h files is highlighted like general text. Before that I saw float highlighted same as double type (blue in my color scheme).

Initially this issue was discussed in forum:
