Holes inside toilet tank. What's it for?

What are these two holes for inside a toilet tank? I got some water inside while cleaning the toilet tank and I had to get an air compressor to drain out the excess. What I did was filled the tank with vinegar & water until the liquid filled above the two holes, eventually covering it. I initially thought it would drain back into the toilet tank but I didn't see another opening at the bottom. I was wondering if water got inside for future cleaning, if it was even necessary to drain it out. Much appreciate it. ​ P.S. What would have happened if I just left the water sitting inside there? https://preview.redd.it/17ch3anjthu71.jpg?width=2016&format=pjpg&auto=webp&s=ea158ae566d10eda86b980dea5b7ff836908891a submitted by /u/Beginning_Rice6830 [link] [comments]
