Magento2: Static content is deploying for disabled modules

[shkodasv]

Summary (*)

• Original summary from the reporter :

I disable module output for several modules (e.g Checkout, GiftRegestry) and would like to know how to exclude CSS related to these modules from styles-l/styles-m files? As I don't need to load extra CSS

Preconditions (*)

• reproduced on 2.3-develop

Steps to reproduce (*)

1. Setup vanilla 2.3-develop installation
2. Take a look at the file app/design/frontend/Magento/blank/Magento_Braintree/web/css/source/_module.less, notice the selector .payment-method-braintree is in there and also notice this selector is in no other file in the Magento source code except for this file in the Magento_Braintree module in the
   Magento/Blank theme.
3. Now disable that module (and its dependency): bin/magento module:disable Magento_Braintree Magento_BraintreeGraphQl
4. Remove potential left over files: rm -R var/view_preprocessed/* pub/static/*
5. Run static content deploy: bin/magento setup:static-content:deploy -f --theme Magento/blank en_US
6. Look at the generated file pub/static/frontend/Magento/blank/en_US/css/styles-m.css

Expected result (*)

• Not finding a reference to the selector .payment-method-braintree

Actual result (*)

• Finding references to the selector .payment-method-braintree

Update: In hindsight, @shkodasv is talking about the deprecated "disabling module output" feature of Magento which was removed in Magento 2.2 I believe. But the issue is still valid for disabled modules as well, or should we open a new issue then?

@shkodasv: I think you have a very valid point here.

@engcom-Bravo: in my opinion this is a bug and I'll re-open this ticket for now, feel free to discuss if you don't agree.

Steps to reproduce:

• Setup vanilla 2.3-develop installation
• Take a look at the file app/design/frontend/Magento/blank/Magento_Braintree/web/css/source/_module.less, notice the selector .payment-method-braintree is in there and also notice this selector is in no other file in the Magento source code except for this file in the Magento_Braintree module in the
  Magento/Blank theme.
• Now disable that module (and its dependency): bin/magento module:disable Magento_Braintree Magento_BraintreeGraphQl
• Remove potential left over files: rm -R var/view_preprocessed/* pub/static/*
• Run static content deploy: bin/magento setup:static-content:deploy -f --theme Magento/blank en_US
• Look at the generated file pub/static/frontend/Magento/blank/en_US/css/styles-m.css

Expected result:

• Not finding a reference to the selector .payment-method-braintree

Actual result:

• Finding references to the selector .payment-method-braintree

Update: In hindsight, @shkodasv is talking about the deprecated "disabling module output" feature of Magento which was removed in Magento 2.2 I believe. But the issue is still valid for disabled modules as well, or should we open a new issue then?

[engcom-Bravo]

Ok @hostep, I'll check it.

[shkodasv]

@hostep Thanks for your reply. You are right "Disable module output" is deprecated. I didn't know it. But in case of disabling the module the same logic should work IMHO - no css should be included.

@hostep I reproduced the behavior following the steps You have provided. But I still better question my Lead on it before confirming the issue. Hopefully tomorrow I'll be back with the result.
