Co2 Absorption With Wet Leaves?

Howdy, all! I'm about to start my first paludarium after years of dabbling with planted tanks, and I'm planning to use aquatic plants grown emersed throughout. I want to do this so I don't have to worry about drainage or constant saturation, but a thought recently occurred to me and I haven't been able to figure it out on my own. Would having the leaves of an emersed plant constantly wet interfere with its ability to pull CO2 freely from the atmosphere? In other words, would the thin layer of water have a limiting effect similar to submersion, or would it be negligible?

Thanks in advance for any assistance!

I would say it shouldn’t be a problem, but I am no expert, however, it’s similar to conditions plants face in many areas where there is constant rainfall for days (pacific NW, many rain forests) and plants don’t have issues.
