Steps to reproduce

• Create basic application using vue create
• Add Electron using vue add electron-builder
• Create a SFC with V-bind() function in CSS block
• Upgrade Electron

What is expected?

V-Bind() should work as normal, creating a var and then replacing V-Bind() with var(--created-var)

What is actually happening?

V-Bind() is not creating a CSS variable, resulting in the styling not being applied

----- Before Updating Electron ----
CSS:

In DevTools:

Note: the variable is defined and I can hover to see the value.

---- After Updating Electron ----

Downgrading Electron fixes the issue but isn't a valid option
