What steps will reproduce the problem?
Not sure how to reproduce this but you can see this problem on gerrit-review.googlesource.com:
1. go to https://gerrit-review.googlesource.com/#/c/17380/9 and see that in patch set 9 the file 'gerrit-sshd/src/main/java/com/google/gerrit/sshd/commands/CreateProject.java' was deleted and that the same file is contained as modified in the previous patch set
2. open the file diff for this file in patch set 9: https://gerrit-review.googlesource.com/#/c/17380/9/gerrit-sshd/src/main/java/com/google/gerrit/sshd/commands/CreateProject.java
3. see that the formatting is correct (comparing base with patch set 9)
4. compare patch set 8 and 9 and see that the formatting is now incorrect

What is the expected output? What do you see instead?
When comparing the file between patch set 8 and 9 it is expected that the user can see that this file was deleted in patch set 9 (left side should be formatted in red, right side should be blank). Instead it looks like the file was not changed between patch set 8 and 9.

Please provide any additional information below.
There is also another stange behaviour in this screen. Trying to show the skipped lines does not work (each time when trying to expand the lines before the block, the first line of the file is shown one more time; trying to expand the lines after the block has no effect).
