Last tag by alphabetical order is ignored

• XE 1.9 SNAPSHOT 17115
• Blank wiki - no tag inserted yet
• Go to the Information tab on Main.WebHome
  • Insert "Tag" in the Tags field & click on "Save"
  • Reload Main.WebHome => the page says no tag has been added yet
• Go to the Information tab on Sandbox.WebHome
  • Insert "Tag" in the Tags field & click on "Save"
  • Go to Main.WebHome => the page still says there is no tag on the platform
• Go to the information tab on Main.WebHome
  • Add "Tag1" in the Tags field & click on "Save"
  • Reload Main.WebHome => the page displays only the "Tag" tag
• Go to the Information tab on Sandbox.WebHome
  • Add "Tag2" in the Tags field & click on "Save"
  • Go to Main.WebHome => the page displays only the "Tag" and "Tag1" tags
• Go to the Information tab on Main.WebHome
  • Add "Tag3" in the Tags field & click on "Save"
  • Reload Main.WebHome => the page displays only the "Tag", "Tag1" and "Tag2" tags

Thus it looks like the last tag in the tag list (by alphabetical order) is ignored by the system. This also means that when only 1 tag is entered in the platform, it will not be displayed on the homepage.

UPDATE: there seems to be another issue at play here:

• Main.WebHome has the following tags: Tag Tag1 Tag3
• Sandbox.WebHome has the following tags: Tag Tag2 Tag4
• However on the homepage all tags have the same size although "Tag" should be bigger (which means than one of the 2 "Tag" tags is ignored)
