несколько простых примеров, в которых они возникают естественным образом.

This is due to fact that you modify your list when iterating it. You can check what's going on with pythontutor.com visualizer or add some print statements like this:

    templist = ['', 'hello', '', 'hi', 'mkay', '', '']
    
    for i, element in enumerate(templist):
        print("Step", i)
        print('element is', repr(element), 'and templist is', templist)
        if element == '':
            print("element is empty")
            templist.remove(element)
