[QGIS-Developer] QGIS3 plugin migration issue

[André William]

After some digging, I found that while the textShortHelp object is not
directly available in the AlgorithmDialog class anymore, i was able to
access it like this:

shortHelpObj = dlg.findChild(QTextBrowser, 'textShortHelp')
>
Is this the expected behavior?
