DateAxisItem does not show when inverted

[Kentin Prat]

My DateAxisItem axis is not displayed when calling the invertY() function. To be precise the values that we would normally see on the axis disappears. It does work if it's a normal AxisItem or if we don't call invertY() but I want it inverted. Here is my code example :

```

import pyqtgraph as pg

from PyQt5.QtWidgets import QApplication

app = QApplication([])

plot = pg.plot()

x = pg.AxisItem(orientation="top")

y = pg.DateAxisItem(orientation="left")

plot.getPlotItem().hideAxis("bottom")

plot.getPlotItem().setAxisItems({"top": x, "left": y})

plot.getPlotItem().getViewBox().invertY(True)

app.exec_()

```

Is it a bug or did I do something wrong ?

 This looks like a bug to me, and I can confirm the behavior on my system. Time, apparently, refuses to run backwards 😁

Would you like the honors of filing an issue? You're most of the way there already.

Done  DateAxisItem does not show when inverted · Issue #1635 · pyqtgraph/pyqtgraph (github.com) 
Do you have an idea about how I could go around this issue since I don't expect it to be fixed right away ?
