Caps Lock key stops functioning as the sprint bind after using in-game chat or signs.

Hello, I am experiencing an issue in Minecraft Bedrock Edition regarding the "Sprint" key binding. I use the Caps Lock key for sprinting. However, whenever I use the keyboard to type in the chat or on a sign, the Caps Lock key stops working as a sprint button. Even after closing the chat/sign interface, I cannot sprint using Caps Lock unless I restart the game. This happens consistently after any text input activity.
