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 having multiple inputs on one row, one input per cell, inside a table with one or more sticky columns the TAB key navigation is focusing at some point on an input that is hidden under the sticky columns, making the focus out of sight, but still inside the table.
The current behavior it's not compliant with the latest accessibility guidelines (WCAG) that states that an element that is focused needs to be in sight. (ref link: https://www.w3.org/WAI/WCAG22/Understanding/focus-not-obscured-minimum)
### Reproduction
StackBlitz link:
https://stackblitz.com/edit/r22tvc?file=src%2Fexample%2Ftable-sticky-complex-flex-example.html
Table state:
- have horizontal scroll (requires a higher number of columns)
- one or more columns sticky
- on at least one row have an input on each cell
Steps to reproduce:
1. Scroll the table in order to hide some columns under the sticky columns
2. Focus first inside the first cell of the row with the inputs
3. Press TAB key in order to navigate through the inputs
4. The focus at some point is on the input that is hidden under the sticky columns
### Expected Behavior
The focused element should be in sight, visible, not hidden under the sticky columns.
### Actual Behavior
The focus is hidden under the sticky columns, out of sight.

Inizia con la riproduzione StackBlitz in src/example/table-sticky-complex-flex-example.html e riproduci il problema usando lo scorrimento orizzontale, colonne sticky e input in una riga. Verifica la correzione passando con il tasto Tab attraverso ogni input e confermando che l’elemento con il focus rimanga visibile invece di essere oscurato dalle colonne sticky.
