Keys not displayed for a dict with float keys

Description

What steps will reproduce the problem?

Problem was caused by trying to reset a key name in the popup window of a dict in the variable explorer.

Cause: Creating a dict usually with a float number as a key is allowed. So i did. create a list with floats as keys and created a dict like:

Temps = [np.float64(1), np.float64(2)]
dummy = {}
for T in Temps:
    dummy[T] = {}

The code does work but the key is not showing up in pop up window after doubble clicking dummy in the variable explorer, even though it is shown in the explorer and is callable as usual.

Ater trying some things i found out that the problem was the float64 type of my listmembers. So a fix was

for T in Temps:
    dummy[float(T)] = {}
