Uneven Padding/Insets for Sum, Integral, etc.

[swiftly-viper]

Hello!

This is an awesome package that has been really helpful in my recent projects.

However, I noticed that for certain latex equations, namely those utilizing "\int" or "\sum", for example, a coloured background reveals inconsistent insets or vertical padding. This isn't a functionality issue, the package works great, it's more of a UI issue. I was wondering if there was a possible solution you could recommend. It is particularly noticeable when both text and display math are combined.

Thank you for the awesome package and your time.
