The Bug
When flying, stuff like cobwebs and vines don't slow you down, so this shouldn't either. Its also worth noting that while doing these things, the player isn't slowed down while flying up or down, just in a horizontal direction.
Affected Actions
-Eating/Drinking
-Loading Bows or Crossbows
-Looking through spyglasses
-Throwing Tridents
Steps to Reproduce
Switch into creative mode and begin flying horizontally at a constant speed.
Perform any of the actions listed above, for example, eat some food.
Take note as to whether or not horizontal flying speed in creative mode is slowed down when performing several actions.
Observed Behavior
Horizontal flying speed in creative mode is slowed down when performing several actions.
Expected Behavior
Horizontal flying speed in creative mode would not be slowed down when performing several actions.

Whether or not all of these are applicable or valid for this issue, here are other actions to note that slow down the player while flying:
Using a brush on suspicious sand/gravel
Using a shield
Throwing an ender eye, and holding the use button down after. (MC-107185)
Chandler
Other actions like using a bow or eating also slow you down, so I don't think this is a bug.
