When you have a long text, it wraps to new line which is then hidden as height is fixed at 13px.

To reproduce

• try to publish a page with a "long" path such as /demo-project/service/dummy-events/another-event-1
• go to Pulse, the new task will show up on top of the list with its title truncated
• mouse over the title will display a tooltip with the whole title but part of it wraps to next line and it's hidden

On 5.2.x, given we don't have Tasks there one way to test it is the following

• rename /demo-project/service/dummy-events/another-event-1/ as e.g. another-event-1-veeeeeeeeeery-looooooooooooooooooooooooooooooooooong-naaaaaame
• select the node
• mouse over on the node path displaying in the table footer
