ui5-dialog: [AXE] ARIA dialog and alertdialog nodes must have an accessible name

[GongRichard]

Describe the bug
AXE issue: ARIA dialog and alertdialog nodes must have an accessible name

To reproduce
Steps to reproduce the behavior:

1. Go to page https://github.wdf.sap.corp/pages/xweb/goalmanagementx/app.html?mock#/goal-detail?targetUserId=undefined&templateType=tgm&templateId=583&id=11003
2. click +12 avatar on the right bottom of Goal Alignment section of the page
3. use AXE browser plugin to scan the page, it will show one serious error related with ui5-dialog.

Actually the dialog already defines aria-labelledby property, I don't know why AXE still reports this error.
BTW, all the dialogs in our project have this issue.

There is aria-labelledby, but the tool does not detect it
