Show enclosing statement when clicking closing brace '}' (like Arduino IDE 1.x) #2867
Description
Describe the request
In Arduino IDE 1.x, when the cursor is placed at a closing brace }, the opening statement is shown in a tooltip on the tab bar:
This allows the user to quickly get an understanding of context of code they are viewing and facilitates navigation through the code in large sketch projects.
Please add this feature to Arduino IDE 2.x.
Describe the current behavior
In Arduino IDE 2.x, only block highlighting is available, which makes navigation in large sketches difficult.

Additional context
A somewhat similar feature is present in the framework upon which Arduino IDE is built:
https://code.visualstudio.com/docs/editing/editingevolved#_breadcrumbs
That "breadcrumbs" feature is intentionally disabled in Arduino IDE. This makes sense as a default in order to provide a carefully curated UI that will be approachable to beginners. However, it also makes sense to allow advanced users to enable additional UI components according to their preferences. This should be supported via the breadcrumbs.enabled advanced setting. However, that setting currently has no effect due to the breadcrumbs feature having been disabled in the source code instead of only through configuring a default for that setting. The task of restoring support for breadcrumbs.enabled is tracked in #1733. That could serve as a partial resolution for this request. It is not functionally equivalent to the Arduino IDE 1.x feature due to only providing function level granularity, while the Arduino IDE 1.x feature provides information about blocks nested within a function.
