Code action to convert single line to multiline (and vice versa)

[BlackBerrius]

I'd like to ask about the feature allowing conversion from single line to multiline (and vice versa).
I'm using Visual Studio Code (current, 1.91.1) and Bicep extension (0.29.47 downgraded to 0.25.53 for testing)
Bicep VS Code extension 0.25.53 was the last version that allowed usage of code action [Ctrl+.] to 'Convert to single line' / 'Convert to multiline'.
For example @allowed values below:
Single line

@sys.description('High availability mode for a server')
@allowed([ 'Disabled', 'SameZone', 'ZoneRedundant' ])
param modeHA string = 'Disabled'

Multiline

@sys.description('High availability mode for a server')
@allowed([
  'Disabled'
  'SameZone'
  'ZoneRedundant'
])
param modeHA string = 'Disabled'

Following the upgrade to Bicep extension version 0.26.54 and subsequent versions, a conversion option has disappeared. Was this planned?
