Describe the bug When using series.show datalabes, on a stacked graph, labels will be overlapped

Version of the card Version: 1.7.1

To Reproduce This is the configuration I used:

type: 'custom:apexcharts-card'
cache: false
stacked: true
graph_span: 7d
header:
  show: true
  title: FV Giornaliero
span:
  end: day
series:
  - entity: sensor.solaredge_power_production_template
    invert: true
    show:
      datalabels: true
    color: green
    name: Produzione
    unit: kW
    float_precision: 2
    curve: smooth
    type: column
    group_by:
      func: max
      duration: 1d
  - entity: sensor.solaredge_power_consumption_template
    show:
      datalabels: true
    color: red
    curve: smooth
    name: Consumo
    float_precision: 2
    unit: kW
    type: column
    group_by:
      func: max
      duration: 1d
apex_config:
  chart:
    height: 130%

Screenshots If applicable, add screenshots to help explain your problem.

Expected behavior Green labels are missing because overlapped by red one.

That is unfortunately not something I can fix, it's how ApexCharts behaves :(
