[Minimum-Spanning-Trees_Simulation] Simulation getting stuck

[Bhuvanesh09]

Defect description:

The Simulation does nothing when the escape button is pressed after drawing the graph. Which gives the user no button or UI to interact with and hence forcing the user to close the simulation.

Steps to reproduce the issue:

• Visit the following link and open the simulation http://cse01-iiith.vlabs.ac.in/exp9/Simulation.html?domain=Computer%20Science&lab=Data%20Structures
• Click on Draw
• Insert any node.
• Press Escape
• Click on Draw again to go to edit mode.
• Now there is no way to exit this edit mode.
• z and esc don't work anymore. :cry:

Actual result:
