a top pipeline named A
many subpipeline named M1,M2...
1.start build A,buildId is 1,call two subpipeline M1 and M2
2.M1 is finished ,M2 is pending
3.use url "A/1/wfapi" to get pipeline stages info
i can see M1 status is SUCCESS,M2 status is IN_PROGRESS
M1 status is SUCCESS,M2 status is SUCCESS
so why the wfapi can't get real status ,or is any way to get the real status?
