Sharemap include parameter thematic style expanded

[johnnyblasta]

Is your feature request related to a problem? Please describe. It would be nice if the thematic style in the legend is expanded when creating a sharemap link it would be included in the link and reflect the expanded state when using the sharemap link.

Describe the solution you'd like Those layers that style is expanded in the legend should be indicated in link.

Describe alternatives you've considered Default closed and only include in link if expanded, so not to build long links.
