Describe the bug
Pressing on Slider row title in block Settings cause the whole row to blink (ripple effect)

To Reproduce
Steps to reproduce the behavior:

1. Add Spacer block
2. Open Spacer settings
3. Press on Slider row title
4. See the whole row has ripple effect (which I suppose shouldn't happens)

Reproduce the same for Gallery and see how Stepper control behaves

Expected behavior
I think the Slider should behave in the same way as Stepper (in Stepper pressing on title do not cause whole row to blink)

Screenshots
Below GIF shows how Gallery Stepper behaves vs how Spacer Slider behaves.
