False Positive "Variable Assigned but Not Used" in Style Tags

[thagxt]

Description:

Theme check is incorrectly identifying variables assigned or captured within a {% liquid %} tag as assigned but not used. This occurs even though the variables are then used with echo withinstyle .

Steps to Reproduce:

1. Create a Liquid template file.
2. Inside a style {% liquid %} tag:
   • Assign a variable using {% assign shopName = shop.name %}.
   • Capture content using {% capture example %} and echo 'Shopify' {% endcapture %}.
   • Use echo to output the captured content (echo example) and the assigned variable (echo shopName).
3. Run the linter or theme check.

Expected Behavior:

The linter should not report any errors for the assigned or captured variables since they are used within the style tag.

Actual Behavior:

The linter flags an error message stating "The variable is assigned but not used."

Source Code:

{%- liquid
                              
assign shopName = shop.name

capture example
  echo 'Shopify'
endcapture
                            
 style
  echo example
  echo shopName
endstyle
-%}

Additional Information:

• OS: Mac
• OS Version: Latest
• Theme Check Version: Latest

👋 thanks for reporting, im able to repro and it seems related to style/endstyle being used around the variable example. when i remove that liquid, the linter stops returning that error
