Reproduction steps:
1. Create a new project
2. Install the Shader Graph package and create a blank Shader Graph
3. Create a sticky note inside the newly created Shader Graph
4. Double-click it to start inputting text into the body
5. Hold the 'p' key on your keyboard
6. Observe the sticky note
Expected result: the 'p' symbol is continuously added to the text field
Actual result: only 1 symbol is added and nothing happens afterwards
