`opsbar-operations` plugin location does not render WebItem's `param` in anchor element

Issue Summary

Contrary to what's described in https://developer.atlassian.com/server/jira/platform/web-item/ (refer to screenshot below), the `opsbar-operations` plugin location does not render WebItem's `param` in anchor element.

Steps to Reproduce

With below web-section & web-item nodes added to atlassian-plugin.xml:

    <web-section key="bar-web-section"
                 location="opsbar-operations"
                 weight="0">
        <label key="bar-actions.label"/>
    </web-section>
    <web-item key="bar-web-item"
              section="bar-web-section"
              weight="10">
        <label key="Bar Action"/>
        <link>/test</link>
        <param name="bar_param_name">bar_param_value</param>
        <styleClass>bar-class&amp;lt;/styleClass>
        <tooltip>This is bar's tooltip.</tooltip>
    </web-item>

Expected Results

The `bar_param_name=bar_param_value` param is rendered as an attribute in the anchor element.

Actual Results

The generated html for the anchor link is

<a id="[plugin-key]:bar-web-item" title="This is bar's tooltip." class="aui-button toolbar-trigger bar-class" href="/jira/test" resolved=""><span class="trigger-label">Bar Action</span></a>

The `bar_param_name=bar_param_value` param is not rendered as an attribute in the anchor element.

Notes

The issue was first raised by the plugin vendor (for ASW Service Catalog project) as question #23 in https://ecosystem.atlassian.net/wiki/spaces/AWS/pages/714571788/Questions+Log.

They referred to https://developer.atlassian.com/server/jira/platform/issue-view-ui-locations/#adding-custom-sections-and-items for adding the new web-section & web-item.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
