allow aligning hovertext for annotations

It looks like there is no way to control the text justification for annotation hovertexts. For example:

# Make an background image
f = px.imshow( [[255]*6]*3, origin='lower')

# Add two annotations with hovertext
f.add_annotation( x=1, y=1, text='left', hovertext='Will be left justified<br>*', showarrow=False)
f.add_annotation( x=5, y=1, text='right', hovertext='Will be right justified<br>*', showarrow=False)

# Tighten the plot
f.update_layout( margin={'l':0, 'r':0, 't':0, 'b':0}, coloraxis_showscale=False)

# This will not apply on the annotation hovertext
f.update_layout( hoverlabel_align='left') 

# This does not exist and annotation hovertexts default to auto
# f.update_annotations( hoverlabel_align='left')

f.show()

The image hovertexts will be all properly left-justified, but the annotation hovertexts will default to 'auto', with the left one being left-justified, and the right one being right-justified. Am I missing something, or this is an omission in the tunable options? Is there some other way to force left-justification on the annotation hovertexts? I produce a set of tables that way that look atrocious otherwise.

Thanks!

Comece pelas APIs de annotation mostradas em f.add_annotation e pelo comportamento de hoverlabel_align em f.update_layout; em seguida, rastreie como as opções de hovertext das annotations são expostas. O trabalho estará concluído quando os hovertexts das annotations puderem receber uma configuração explícita de alinhamento, incluindo os exemplos de alinhamento à esquerda e à direita descritos na issue.
