Ocelots cannot be tamed when using keyboard and mouse

Steps to reproduce
-spawn ocelot.
-hold raw fish.
-wait for ocelot to come to you.
-right click ocelot multiple times with fish and expect the ocelot to be tamed.
Nothing happens...

Just to clarify, I am using a PC running Minecraft Windows 10 edition with full keyboard and mouse NOT a touch screen device. This game can also be played with a controller.
