Descrizione

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

When the tooltip component overflows a parent sidenav and its text content is updated dynamically, it hides.

We have debugged the code, and this happens because the sidenav component extends the cdk-scrollable.

The piece of code that calls the tooltip hide function is the following:
https://github.com/angular/components/blob/bae953999407fd385b1d571e04350bf0f28abf05/src/material/tooltip/tooltip.ts#L510-L520

### Reproduction

Stackblitz url:
https://stackblitz.com/edit/stackblitz-starters-wbd1hh?file=src%2Ftooltip-sidenav%2Ftooltip-sidenav.component.html

As you can see on the stackBlitz example, we have two tooltips:
- The tooltip inside the sidenav, which overflows the sidenav component. That if we update the tooltip text, the tooltip disappears. (BUG)
- On the other hand, we have the tooltip inside the mat-sidenav-content which works properly, and it doesn't hide after updating it. (WORKS WELL because doesn't overflow the parent)

### Expected Behavior

The tooltip inside the sidenav should not hide when the text is updated.

### Actual Behavior

The tooltip placed inside the sidnav that overflows is hidden suddenly when the text is updated.

### Environment

- Angular: v16.2.4
- CDK/Material: v16.2.3
- Browser(s): Google chrome Versión 116.0.5845.187, Firefox 117.0
- Operating System (e.g. Windows, macOS, Ubuntu): Windows

Direzione di ricerca

Start with src/material/tooltip/tooltip.ts around lines 510-520 and reproduce the issue using the linked StackBlitz example. Compare the overflowing tooltip inside mat-sidenav with the working tooltip inside mat-sidenav-content, then run the relevant tooltip and sidenav tests if available. Done means updating the overflowing tooltip text no longer hides the tooltip.
