Entering a big number into the "Target Frames Per Second" in Profiler's Preferences inconsistently converts it either to 1FPS or 1000FPS

How to reproduce:
1. Create a new Unity project
2. Go to Window -> Analysis -> Profiler
3. Under the "Highlights", Target Frame Time -> Custom -> Target Frames Per Second
4. Enter the number with at least 5 symbols, press enter and observe the results
5. Enter the number with at least 16 symbols, press enter and observe the results
6. Compare the results

Expected results: Both times the shortened number is the same
Actual results: The value is shortened to the 1000 for the first time and to the 1 the second time

Reproducible with: 6000.0.57f1, 6000.2.2f1 , 6000.3.0b1

Reproducible on: macOS Sequoia 15.6 (M1)
