Out of nowhere, some time after playing Minecraft normally in 1.14.1, I was not able to simply click on items to move them around my inventory. I later discovered that I had to hold-click to move them, even for shift-clicking. This occurred in both pre and post issue made worlds.

Is touchscreen mode enabled?

--No. I didn’t even know you could enable that on Java.--
Sorry. I was certain touchscreen mode was off because I was not on settings to enable anything when the issue came about. Now I realized that I must've pressed a button accidently and turn on touchscreen mode, which is the reason for this issue. Resolved.
