useColumnBasisZero:false not applied in production builds

[gerardcarbo]

Bug Report

What is the expected behavior?

When FlexLayoutModule.withConfig({useColumnBasisZero: false}) is specified, fxFlex default output shoud be flex:1 1 auto

What is the current behavior?

In production builds it still produces flex: 1 1 1e-9px

What are the steps to reproduce?

Install:

https://github.com/gerardcarbo/flex-layout-test

and run:

npm build && npm start

The span where fxFlex is applied has the style:

style="flex: 1 1 1e-09px; box-sizing: border-box"

If you run:

ng serve

the same span has the style:

style="flex: 1 1 auto; box-sizing: border-box;"

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Is there anything else we should know?

To generate the test I just ran ng new, configured --prod flag and added the fxFlex to the span after installing @angular/flex-layout module

In both cases, using latest version of Flex Layout, I'm getting flex: 1 1 auto, which is the intended behavior. I'm closing this issue, but if another demo is provided we can reopen.

I've published the output of the production build (--prod) of the provided sample using ngh in:

https://gerardcarbo.github.io/flex-layout-test/

As you can see, using the latest @angular/flex-layou 7.0.0-beta.23, it sets flex: 1 1 1e-09px to the span:

I can not provide you a stackblitz demo because the problem is in the production build (ng build --prod) but I have rechecked in a clean ubuntu instalation and you can reproduce the bug with:

sudo npm install -g npx 
git clone https://github.com/gerardcarbo/flex-layout-test.git
cd flex-layout-test/
npm install
npm run build
npm run serve_build

I don't know if that helps, on my app:
With 7.0.0-beta.21, I am experiencing the issue.
7.0.0-beta.20, I don't have the issue but my app layout is a mess.
With 7.0.0-beta.19 I don't have the issue.

Issue still exists in 7.0.0-beta.24
