fix: Bug# 点击自定义主题后未确认，菜单勾选状态错误

[DaiZW007]

由于自定弹窗结果返回是异步的，所以修改为:
每次菜单点开重新进行勾选

Log: 点击自定义主题后未确认，菜单勾选状态错误

Hi @DaiZW007. Thanks for your PR.

I'm waiting for a linuxdeepin member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
