@Doraemon012 why does the page goes blank after you delete a step? could it be fixed ?

[Doraemon012]

@ABHISHEK-PANDEY2

• The issue of the page going blank was due to the code addressing variables related to the deleted step (e.g., currentStep, stepData, etc.).
• I found a related PR Fixed #931 Fix Out-of-Bounds Issue  #932.
• I've confirmed it works.
• Merging both the PRs (fix: Removed the step feature in delete #977 and Fixed #931 Fix Out-of-Bounds Issue  #932) will fix the issue of the page going blank and as well as the issue of Inconsistent Data Removal.

@ABHISHEK-PANDEY2 @shivareddy6 @Doraemon012 [This issue yet not FIXED] lets explain, this issue is not fixed totally the problem in which is this when we delete the second step the whole page is reloaded and become blank but this effect does not occurred when we delete the other step (when count of steps is greater then 2)

But steps is greater than 2 (>2) then it work fines

Demonstration what i said :
here is some video (the branch is up to date )
