Start editing an Oozie workflow.
Narrow the browser window so that the big blue Actions icons no longer fit in a single row, they wrap to a second row. For me, it happens at around 1050px width.
The workflow's name doesn't appear (is hidden by the 2nd Actions row) and hence it's impossible to rename it.
My browser's window is usually approximately just as wide so that the last Action icon wraps to the second line. This is because I don't like fullscreen windows, I have the browser tabs on the left. Most of the homepages just have useless whitespace on the two sides at wider window, and they work perfectly with a width of 950–1050-ish pixels. Anyways, this is simply what I'm used to.
Expected: Either smaller Actions icons, or not covering the workflow name when wrapped in two lines, so that the UI is fully functional at a bit narrower size. Or a warning to widen the window.
