Function calls break into multiple lines after 17 string concatenations

.stylua.toml:

column_width = 80
line_endings = "Unix"
indent_type = "Spaces"
indent_width = 2
quote_style = "AutoPreferSingle"
call_parentheses = "None"

Example code:

local function foo(...) end
local function long_function_name() end

local function test()
  return 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. foo(long_function_name())
end

In the above example, concatenate another 'test' and run the formatter. It will break the function call as:

local function foo(...) end
local function long_function_name() end

local function test()
  return 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. 'test'
    .. foo(
      long_function_name()
    )
end

I don't know if it's a bug or not, but this seems like a weird edge case.

Yep, looks like a bug. We probably aren't resetting the shape properly
