'Recently used absolute ranges' list contains duplicate ranges

[ein-stein-chen]

What happened:

The 'Recently used absolute ranges' list in the time picker shows the same time range multiple times.

What you expected to happen:

The 'Recently used absolute ranges' list in the time picker does not show duplicate ranges.

How to reproduce it (as minimally and precisely as possible):

• Open a dashboard
• Open the time picker and enter an absolute time range (and click on 'Appy time range')
• Open the time picker and click on the time range in the 'Recently used absolute time ranges' list that was entered in the step before
• Open the time picker and see the same time range showing up multiple times in the 'Recently used absolute time ranges' list

Anything else we need to know?:

It would be nice to increase the limit of the recently used absolute time ranges list and make it scrollable like the 'Quick ranges' list.

Environment:

• Grafana version: 9.2.4 (64017e8)

• User OS & Browser: Linux, Firefox & Chromium
