Issue description

When changing a specific animation (eg. animation_a) FPS if you click on another animation name (eg. animation_b), the new FPS value is assigned to both animations.

Steps to reproduce

• Create two animations
• Select one animation
• Click on FPS input and change to a new value
• Click on another animation name
• Now both animation with have the same FPS value.

Minimal reproduction project

Doesn't need a specific project, just create a new project and a new AnimatedSprite2D and assign new sprite frames and follow above steps.

I am trying to solve this bug and the the relevant class is SpriteFramesEditor defined in the file sprite_frames_editor_plugin.h.

The problem is due to a value_changed signal emitted with the old value of the anim_speed field.

For some reason this signal is emitted after the _updated_library function is executed but still with the old value, but I can't find out what is triggering this signal. If anyone has an idea why this is the case, I would appreciate an explanation.
