Expected Behaviour
---@alias SampleCount # fractions for reduced resolution
---| 0.125 # 9 bit sample
---| 0.25 # 10 bit sample
---| 0.5 # 11 bit sample
---| 1 # 12 bit sample
---| 2 # 2 12 bit samples
-- ...
0.125, 0.25 and 0.5 are correctly identified as numbers and treated accordingly
Actual Behaviour
0.125, 0.25 and 0.5 are labeled as "Undefined type or alias"

Research direction
Reproduce the issue in a Lua file using the reported alias and enum example, then trace how fractional values are parsed and classified in aliases and enums. Done means 0.125, 0.25, and 0.5 are recognized as numbers without an “Undefined type or alias” diagnostic.
