[bug] osc 8 flooding

[phanen]

Describe the bug

Too many osc8 requested to the terminal.

Using a neovim terminal (v0.10.0+) to reproduce (this command launch a lazygit in nvim terminal, and nvim will echo all terminal request in error level):

mkdir /tmp/tmp; cd /tmp/tmp; git init
nvim -u NONE +"au TermRequest * echoerr v:termrequest" +"term ./lazygit -ucf /dev/null"
# this way can check this without attach tui
# nvim --headless -u NONE +"au TermRequest * echoerr v:termrequest" +"term ./lazygit -ucf /dev/null"

Then hit enter and enter again and again, you will see endless ^[]8;;:

I bisected and found this problem didn't exist before this: 524bf83.

Expected behavior
There shouldn't be too many OSC 8 request.

Additional context

• neovim 0.10.0+

After debugging for a while, I found this seems a upstream problem...

524bf83 cause this by bump tcell (v2.5.1 -> v2.5.2), which will tputs this on each drawcell:

lazygit/vendor/github.com/gdamore/tcell/v2/tscreen.go

Lines 900 to 907 in 5e26183

	// URL string can be long, so don't send it unless we really need to
	if t.enterUrl != "" && t.curstyle != style {
	if style.url != "" {
	t.TPuts(ti.TParm(t.enterUrl, style.url, style.urlId))
	} else {
	t.TPuts(t.exitUrl)
	}
	}
