Terminals created via "New terminal (Select a container)" have incorrect wrapping until the window is resized

[amisevsk]

Describe the bug

Terminals created through "New Terminal (Select a container)" appear to be created with the default width (80 characters?). This results in incorrect handling of text, with lines longer than 80 characters breaking the terminal. If the browser window is resized, it appears that the correct dimensions are sent to the terminal, and it begins behaving normally.

Che version

7.75@latest

Steps to reproduce

1. Start a workspace
2. Open a terminal by navigating Terminal -> New Terminal (Select a Container)
3. Type a line longer than 80 characters -> text wraps back to beginning of line, overwriting earlier text
4. Resize the browser window
5. Terminal behaves as expected

Expected behavior

Terminals created through "New Terminal (Select a Container)" should behave the same as terminals created through "New Terminal"

Reopening issue as there are lingering problems with terminal width -- Code seems to compute character width incorrectly in many cases, with the number of columns changing after the terminal has been initialized (you can see this by changing e.g. the font size for the terminal: eclipse-che/che-machine-exec#277 (comment))

@azatsarynnyy @RomanNikitenko folks, any ideas about this issue? can we raise it on code-oss end?
