### Summary <!-- (required) --> The `uibuilder-common-filter` has elements with fixed width, can't be used in a responsive layout ### Steps to reproduce <!-- (required) --> 1. check out the `bugs/uibuilder-common-filter-min-width-bug` branch 1. start the example app 1. open http://localhost:8080/mdc/nestedCrud 1. add a filter to the grid before that the UI looks fine:  After that the UI is not fine at all:  ### What is the current bug behavior? <!-- (referenced) --> The `uibuilder-common-filter`'s each child has a fix width, so the filter can't be used in a narrower `div`. And the filter-row uses some global styles, so I can't style just that component, I have to redefine those global styles... ### What is the expected correct behavior? <!-- (required) --> I want to resize the `filter-row`s' components. ### Metadata <!-- (required) --> Version:
