"Merge into pattern" error

In a project with C# 9 enabled, given the code:

1 <= index && index <= 26

R# suggests that I "merge into pattern". Doing that results in:

index <= 1 and <= 26

This is clearly incorrect - the first condition has been inverted. The correct code should be:

index >= 1 and <= 26

R# 2021.1.3
