[Trail Renderer] Add Key does not add any keys to trail's Width curve

Visual Effects - Legacy


To reproduce:
1. In any project, create an object with Trail Renderer component
2. In Trail Renderer component, find the Width curve interface
3. Try adding keys to the curve by right-clicking and selecting "Add Key"

Expected: key is added to the selected location on the curve
Actual: no key is added

Reproduced in: 2019.1.6f1, 2019.1.11f1, 2019.2.0b10, 2019.3.0a10
Not reproduced in: 2017.4.0f1, 2017.4.30f1 2018.4.4f1, 2019.1.5f1

Note: it seems like trail's width curve has not been updated to a newer curve interface as opposed to the rest of the curves in the editor (such as in particle system)

    Another type of fuel, the kerosene lanterns are great for campers that aren't afraid to fuel their own gear. These lanterns aren't as easy to use and they come in a few different styles

    You can bypass that by double clicking on curve - it will add new key succesfully.
