[6.x] Remove invisible "link" space that could be accidentally clicked

[jaygeorge]

Description of the Problem

While it's traditional to select entries using the left "checkbox" column, it's also possible—and convenient—to select entries using the white space available in the table rows.

(Select any of these red areas, and you can also select/deselect entries).

The problem is that parts of the title in the listings table contain "invisible" link space. For example, in this screenshot, if I click anywhere in the highlighted purple DOM, I will inadvertently be taken into the entry rather than selecting or deselecting the entry.

This is unexpected behaviour and it's caught me out a few times, especially with shorter titles where the accidental click area is larger.

What this PR Does

The behaviour above is caused by two things:

• Firstly the min/max width values.
  • While I would like to keep them, they require a block-like display value to work, which means we're stuck with the invisible click areas again.
  • I think in this instance, getting rid of the invisible click areas is more desirable for usability.
  • Besides this, min/max has limited utility within table elements, since they tend to naturally balance themselves out, layout-wise.
• Secondly a flexbox layout—which is a block-like display value (even inline-flex in this instance)—causes invisible click areas.
  • Flexbox is certainly desirable here sometimes, so to get around this I've conditionally applied flexbox when there is more than one child. This ensures layouts like _/users, where you have avatars and text, still work.

How to Reproduce

1. Go to cp/collections/something
2. Make sure you have some long titles

• To test the clickable area you could pull the window in and click the "white space" in the tile areas
• You could also test a more complex listings layout like cp/users which contains avatars

Before

This entire block contains a link to go to the entry

After, with the fix

You can see here the entry link wraps nicely around the text
