Inconsistent behavior when providing an array of marker sizes in "markers" mode on scatter3D

When an array of marker sizes is provided in "markers" mode in scatter3D, the displayed size of the markers is half the size displayed when a single value is provided instead of an array. For example, if there are two points on a trace and "[20, 20]" is provided, the displayed markers are displayed at exactly the same size as if only "10" were provided.

Additionally, when you provide an array with fewer elements than points the trace have (for example, a trace with 3 points that is given the array "[20, 20]"), the remaining point markers are sized by default to 10. Maybe that's the expected behavior, but in other charts like scatter2D or scatterpolar the remaining points become hidden (size 0), so I thought it was worth mentioning that too.

(not related but thank you all for your great work! I've been using plotly for a few months now and it's just amazing!)

Reproduza os casos de dimensionamento dos marcadores de scatter3D do CodePen vinculado: compare um tamanho escalar com um array de tamanhos de valor equivalente e, em seguida, tente um array mais curto que o número de pontos. Rastreie o ponto de entrada dos marcadores de scatter3D e verifique se os valores do array correspondem ao dimensionamento escalar e se o comportamento do array curto é intencional e consistente com a expectativa relatada.
