Stop clearing - when editting coordinates and size of things

While using Map Editor, I find that the numeric input fields are often overzealous with their validation.

The validation is quite smooth but if i want to replace the entire input these are the steps I’d follow…

1. Select all in the input field

2. Delete

3. Input what I want, e.x -2500

4. The UI auto clears - because “-” is not a valid number or something.

I have to take round about steps, like…

1. Input 2

2. Move cursor back to start of the number

3. Input -

4. Move cursor back to the end of the number

5. Input 500
