Still some problems with opacity handling in Symbolizer Editor

[verendi]

Bug

Describe the bug

1. For polygons, Fill-Opacity value can be set and is applied and saved to the style, but it does not show up when editing this rule again (so the user cannot see that this value is already set).
2. For points, the Stroke-Opacity works fine, but the Fill-Opacity is not working (is not applied to the style).

To Reproduce
Steps to reproduce the behavior:

1. For the polygons issue, open the Symbolizer Editor in rule of a polygon style and set a Fill-Opacity value. Close the Symbolizer Editor and open it again.
2. For the points issue, open the Symbolizer Editor in rule of a point style and try to set the Fill-Opacity value.

Expected behavior

1. For the polygons issue, the saved Fill-Opacity value should be visible in the Symbolizer Editor.
2. For the points issue, the Fill-Opacity should be applied to the style.

I may have a fix for this, at least if SLD is involved. Will try to cross reference here

We need to be precise on opacity, fill-opacity and stroke-opacity. opacity is missing in the above symbolizer-editors which might be a problem.

only related to SLD 1.1, see https://github.com/geostyler/geostyler-sld-parser/pull/289/files#diff-03b9f5ee99035e0bf89d2385871c79bce270f81666e5bf0cc8e4a13ccbfe3f15L400-R451

Should be fixed with #1374. Pleas try again with version 5.1.0.
