### Steps to reproduce
I don't have any reproduction steps yet
### Example Project
<!-- If possible, please create an example project here on GitLab.com that exhibits the problematic
behavior, and link to it here in the bug report. If you are using an older version of GitLab, this
will also determine whether the bug is fixed in a more recent version. -->
### What is the current *bug* behavior?
Sometimes all file changes are not showing
### What is the expected *correct* behavior?
All file changes should show up
### Relevant logs and/or screenshots
<!-- Paste any relevant logs - please use code blocks (```) to format console output, logs, and code
as it's tough to read otherwise. -->
