How to display custom icons in project sidebar of Jira Server 8.12 ?

It worked alright till Jira Server 8.11 with below approach, but since 8.12 custom icon is not getting displayed in project side bar. What changes that I need to apply on top of below implementation.

atlassian-plugin.xml

<web-resource ...>
  <resource type="download" name="versionmanager.css" location="/versionmanager/versionmanager.css"/>
  <resource type="download" name="version_edit.svg" location="/images/version_edit.svg"/>
  ...
</web-resource>

css file

.some-custom-icon {
 background-image: url("version_edit.svg");
 height:auto;
 width:auto;
}

 web-item in atlassian-plugin.xml

<web-item ...>
  <param name="iconClass" value="aui-icon-large some-custom-icon"/>
  ...
</web-item>

After removing below 2 lines of code from css file, I'm able to render custom icon in project sidebar even in Jira 8.12

 height:auto;
 width:auto;

Thanks !
