Bug Report for https://neetcode.io/problems/trapping-rain-water - Need more test cases

Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.

Below test case or similar should be added, as existing test cases for submission are not restrictive enough.
height= [5, 1, 2, 0, 4]

I tried a very naive and unnecessarily complicated code as below (Python solution):
This solution shouldn't have been accepted as it fails on above test case, but it was accepted due to lack of variety of test cases.

class Solution:
    def trap(self, height: List[int]) -> int:
        left = 0
        right = 1
        max_area = 0
        while(left < len(height)-1):
            if (height[left] == 0):
                left+=1
                right = left+1
                continue
            if height[left+1] >= height[left]:
                left+=1
                right = left+1
                continue
            else:
                area=0
                while(right < len(height) and (height[right]< height[left])):
                    area += height[left] - height[right]
                    right+=1
                if(right >= len(height)):
                    area = 0
                    right = len(height) - 1
                    initial_right = len(height)-1
                    while(left< right):
                        initial_right = right
                        while (height[right-1] < height[right] and left< right):
                            area+= height[initial_right] - height [right-1]
                            right -=1
                            #print(area)
                        right-=1
                    right = len(height)-1
                max_area += area
                #print(left, right, height[left], area)
                left= right
                right = left+1
        return max_area

Below is the response from NeetBot for further understanding:

This edge case reveals a fundamental flaw: the backward scan only captures water in "valleys" that are monotonically increasing as you go rightwards from the left end, ignoring other dips.
