Variables window does not allow unfolding first element of any python data structure

• VSCode Version: 1.19.3 Shell 1.7.9 x64 Arch
• OS Version: Windows 7 Professional
  Extensions used : Python 2018.1.0 from Microsoft

Steps to Reproduce:

1. Create any python data object with multiple elements.
2. While in debug mode, try unfolding the first element of the data object. While the icon changes to unfolded mode, the data element does not populate
3. Try unfolding the successive data element and it works as expected.
   Does this issue occur when all extensions are disabled?: Yes

In the Attachment, please note the unfolded mode for 0th and 1st row of playerData object. Although 0th row icon indicates that it is unfolded, there is no populated data.

Hi @csakumar, thanks for letting us know about this problem. I was unable to reproduce the failure so let's see if we can figure out what I'm doing wrong. :) I'm followed your steps with the following code:

from collections import OrderedDict as OD
data = [
    OD(x=1, y=2, z=3),
    OD(a=1, b=2, c=3),
]
print('done')  # breakpoint here

I'm using version 2018.1.0 (soon to be released) of the Python extension, with Python 3.6 on linux. Could you give my code a try and see if you run into the same problem? Also, what version of Python are you using?

Because it has been more than a month since we requested more info, I'm closing this issue. If you are able to provide the info later then please do so and we can re-open the issue.
