Edit Runtime - unable to modify events section

[ColemanTom]

Reproducible Example

Running this example flow.cylc:

[scheduling]
    initial cycle point = 20201010
    final cycle point = 20201010
    [[graph]]
        R1 = foo

[runtime]
    [[foo]]
        script = false
        [[[events]]]
            failed handlers = echo hello

I look at Edit Runtime in the WUI and see nothing about event handlers in there.

Expected Behaviour

As events is a section within a tasks runtime area, I expected to be able to modify the [runtime][task][events] entries and any defined should be visible.

Can confirm that broadcasting task events does work so this should be reasonably straight forward.
