[Feature Request] EquationBlock's editing is too narrow

[BayMaxBHL]

Description

Can the editing method of EquationBlock be as wide as that of CodeBlock? When editing is finished, a button can be set to express editing completion and display editing results. After all, when you use EquationBlock, you need to edit relatively complex formulas, and the existing narrow editing location is not conducive to editing.

PS: Latex's matrix box behaves like a Bug. Although there may be style design, but in latex, it is better to show the following standard form.
