Iframe embed code is not behaving correctly since 8.15

[yomduf]

Kibana version: 8.15.1

Elasticsearch version: 8.15.1

Server OS version:

Browser version:

Browser OS version:

Original install method (e.g. download page, yum, from source, etc.):

Describe the bug:

• Share dashboard option as Iframe ignore item selected

Steps to reproduce:

1. Use Kibana sample Dashboard

2. Click on share and click embed

3. Select 1 item or nothing

4. The dashboard exposed is equivalent to all item selected

Comparaison 8.14.3 vs 8.15.1 with no item selected in both version

Explanation guess : In 8.15.1 the URL suffix is

?_g=(refreshInterval%3A(pause%3A!t%2Cvalue%3A0)%2Ctime%3A(from%3Anow-7d%2Cto%3Anow))&hide-filter-bar=true

where in 8.14.3 it's

?embed=true&_g=()&hide-filter-bar=true

The ?embed=true& is missing in 8.15.1, adding it solve the issue

Expected behavior: Having an URL that is like this

?embed=true&_g=(refreshInterval%3A(pause%3A!t%2Cvalue%3A0)%2Ctime%3A(from%3Anow-7d%2Cto%3Anow))&hide-filter-bar=true
