Issue 1742: "Open in new tab" doesn't work for large patch set diffs
Status:  New
Owner: ----
Reported by mdemp...@google.com, Jan 2, 2013
Affected Version: 2.5.1-824-g3f2c1d5

What steps will reproduce the problem?
1. Go to https://gwt-review.googlesource.com/#/c/1550/
2. In "Patch Set 2", locate any file you want (e.g., "Commit Message")
3. Click to open the side-by-side diff in a new tab or window (e.g., control-click, or right-click then "Open in new tab" or "Open in new window")
4. The new tab/window loads https://gwt-review.googlesource.com/#/c/1550/2//COMMIT_MSG, but never shows a diff.

Alternatively, just load https://gwt-review.googlesource.com/#/c/1550/2//COMMIT_MSG directly.

What is the expected output? What do you see instead?
I should see a diff.  Instead I see a mostly blank page (only the Gerrit page header/footer are present).

Please provide any additional information below.
This seems to be something specific about change 1550, because this works as expected for other not-quite-so-large changes (e.g., https://gwt-review.googlesource.com/#/c/1420/).  Perhaps related to the fact that it needs to show a progress bar while calculating the patch set when the page is loaded?
