Terminal uses incorrect line count after adding new tab

[ThFabba]

After adding a second tab, the terminal line count reported to applications seems to be wrong in the first tab.

(Resolution: 1024x768)

To reproduce:

• Start Terminal and maximize it
• Terminal -> New Tab (Alt+T)
• Alt+1 to switch back to the first tab
• nano /var/log/syslog
• Note that nano is only showing one menu line (attached screenshot)
• Press Page Down, some text from the previous page will appear instead of the text that should be there ("USER: failed to create the required index ..." in screenshot)
• Page Up, Page Down, second page text now displays right

Same happens again after closing and reopening nano. Does not happen in second tab (Alt+2). Resizing the Terminal window fixes the issue.

Does it still happen in nigltly builds?

Just to clear:

• Start Terminal;

  ~> tput lines
  ~> 37
  

• <Alt-T>

  ~> tput lines  # second tab
  ~> 36
  

That is OK - the tabline was added above and height of terminal view was decreased.

• <Alt-1>

  ~> tput lines  # first tab
  ~> 37
  

That is wrong - the height must be adjusted because change of viewport's height too.

Looks like corresponding window size change signal is not send to the first tab's application after adding/removing tabs.
