No Update (with rebase) button in GEF-Classic repo https://github.com/eclipse/gef-classic/
Similar to #2905 (closed) but for GEF-classic.
From the WB issue:
In platform we have the option to update PR with rebase. It is a button with two options.
Update branch Update with rebase
See for example https://github.com/eclipse-platform/eclipse.platform.ui/pull/348
We do not see this option in GEF-Classic, please enable it.
