Prevent Action Log context chips from overflowing the available content area.

• Context chips remain within the bounds of the Action Log container

• When the number of chips exceeds the available width, the layout handles the overflow gracefully

• Users can access all context chips through an appropriate overflow behavior (e.g. wrapping or horizontal scrolling)

• Action Log layout remains readable regardless of the number of context chips

• Existing Action Log behavior remains unchanged for shorter lists

• No regressions to Action Log spacing, expansion/collapse behavior, or responsiveness

Notes

• This applies to all Action Log entries that render context chips, not just tab-related actions
• Current implementation allows chips to overflow beyond the visible Action Log area when many results are returned

Attachment: Bug 2053889 - Part 1: Add a single row overflow handler

Rows are width-aware by default. They measure themselves and show the items
that fit. Overflowing items are shown behind a "+n more" button. Setting a
fixed item count overrides the width-aware behavior.
