Chrome Version       : Version 69.0.3497.100 (Official Build) (64-bit)
URLs (if applicable) : N/A. Bug is in DevTools
Other browsers tested:
  Add OK or FAIL, along with the version, after other browsers where you
have tested this issue:
     Safari: N/A
    Firefox: N/A
       Edge: N/A

What steps will reproduce the problem?
(1) Open DevTools on any page
(2) Within the Styles section of the Elements panel, hover and then click on the "Add text-shadow" editor button 
(3) Adjusting the spread of the text-shadow will add a fourth numeric value that invalidates the text-shadow property.
(4) Adjusting the outset/inset toggle also invalidates the text-shadow property.

What is the expected result?
The text-shadow property does not support spread or inset/outset and the options are erroneously there. The expected outcome is an editor that affects the x and y offsets, the blur radius and color. 

What happens instead?
The spread and outset/inset options are presented (probably a left over artifact from the box-shadow editor) and altering the options generates invalid code.

See attached screenshot.
