Steps to reproduce the problem:
The script tools/vim/chromium.ycm_extra_conf.py that configures YouCompleteMe for various IDE does not support jumbo builds, https://chromium.googlesource.com/chromium/src/+/master/docs/jumbo.md 

With a jumbo build enabled the script reverts to default build flags rather than printing flags for a jumbo chunk the file is in.

What is the expected behavior?
The tool properly extracts relevant compilation flags event when use_jumbo_build is set to true.

What went wrong?
The tool relies on ninja -t query to get the build target. Unfortunately this does not work for jumbo build as there C++ sources essentially treated as header files included into particular jumbo file and the ninja query tool gives nothing then.

Did this work before? No 

Chrome version: 72  Channel: beta
OS Version: Ubuntu 18.04
Flash Version: 

A possible workaround is to replace ninja -t query with ninja -t deps. The plus of this is that the flags for the header files will be properly detected. The minus is that ninja -t deps takes 2 seconds on a fast Linux laptop.
