map_to_html_table expression function doesn't seem to respect keys order

[DelazJ]

What is the bug or the crash?

Let's use this expression in the expression builder and watch the output

map_to_html_table(
  map(
    'qgis','rocks',
    'gdal', 'rocks also')
)

I would expect "qgis" as first column in the output table and not "gdal".

Steps to reproduce the issue

Well, further testing... It seems that it is the map function that displays an output with keys alphabetically ordered map('qgis','rocks', 'arcgis', 'doesn''t rock', 'gdal', 'rocks also') outputs { 'arcgis': 'doesn't rock', 'gdal': 'rocks also', 'qgis': 'rocks' }

ps: I don't know if this is an issue (or to what extent it would be fixable, as if I'm not wrong, maps do not have order concepts), but I wonder how one could control the map_to_html_table output order (e.g. for display in a maptip)

@DelazJ Yeah you're right the issue here is going to be the map as it ordered by key.

You could make a Python expression function to do your tooltip logic although not as portable as a built in function.

Might be handy to have a to_html function that can take a element type and data and convert it into different elements possibly. So you could do to_html('ul', data) that makes a list from given data.
