jiraIssueContents route twice to url when open an issue

[Tamar]

Here is my atlassian-connect.json:

"jiraIssueContents": [
    {
        "icon": {
            "url": "companyurl/images/abs.svg"
        },
        "target": {
            "type": "web_panel",
            "url": "/requirements?issueId={issue.id}&projectId={project.id}"
        },
        "tooltip": {
            "value": "abs"
        },
        "name": {
            "value": "Linked abs"
        },
        "key": "my-issue-content-panel"
    }
],

when open an issue and click on the new button it's routing to the url  "/requirements" as excepted. 

however, when open the issue again, and the panel is still opened (without clicking on the button, since not hide it after first closed.) it's routing to the url  "/requirements" twice.

any idea why it's routin twice to the url? it's impact the performance?

Thanks
