Shimano shifters act this way when the grease turns to gum. This is a very,
very,
very common issue. My 8-speed XTR shifters did this about 15 years ago- I cleaned them out with spray oil and they still work fine today. I prefer petroleum spray oil over WD-40 because WD-40 tends to turn to gum on its own.
