Running a script that writes a block of code into a textarea on a website.  The first four "lines" write correctly until var url = "https: at which point the cursor jumps to the upper left of the text area and then continues writing.  Each time the / character is come across, the cursor returns to the upper left before continuing writing.
How can I prevent the cursor being affected.
I have tried \/, \\/, {/}, and similar ways to escape the slash.
self.driver.find_element_by_id('textarea').send_keys(
        '\nvar device = this\n\nvar url = "' + baseurl + '/' + firmwarename + '"\n\nvar conv = TR69.createConnection(device)\n\ntry {'+
   'var uuid = java.util.UUID.randomUUID().toString().replace("-","") \n'+
What it physically does:
myhiddenurl.comSG9C130016_prod-mycomponent-5260-8a.27.103-combined-squashfs.img.gsdf"
var conv = TR69.createConnection(device)
var device = this
var url = "http:
Notice that lines 3 and 4 should be 1 and 2. And that line 1 is the continuation of what is now line 4.
Here is sample code which shows the issue...
    firmwarename = "tchrisdemo-code-3-2-3.gsdf"
    self.driver.get("https://futureoftesting.us/os.html")
    self.driver.find_element_by_id('textarea').clear()
    baseurl = "http://myhiddendomain.com/"
    self.driver.find_element_by_id('textarea').send_keys(
        '\nvar device = this\n\nvar url = "' + baseurl + '/' + 
    firmwarename + '"\n\nvar conv = TR69.createConnection(device)\n\ntry {'+
   'var uuid = java.util.UUID.randomUUID().toString().replace("-","") \n'+
   'var dlRequest = new TR69.DownloadRequest() \n' )
Line 5 of the code is the problem...
I've tried a variety of changes akin to your comment. The .format one allowed one allowed one "/" through then jumped to the top of the textarea and continued writing on the next one.
    baseurl = r"http://myhiddendomain.com/"
    url = "{}/{}".format(baseurl,firmwarename)
    self.driver.find_element_by_id('textarea').send_keys(
        '\nvar device = this\n\nvar url = "' + baseurl + firmwarename + '"\n\nvar conv = TR69.createConnection(device)\n\ntry {'+
   'var uuid = java.util.UUID.randomUUID().toString().replace("-","") \n'+
   'var dlRequest = new TR69.DownloadRequest() \nThis is formatting: ' + url) 
which sadly generated this:
    var dlRequest = new TR69.DownloadRequest() 
    This is formatting: http:/myhiddendomain.com/
    var device = this    
Not sure I fully get this solution.
It appears after more searching that the "jumping cursor" is a known problem and that the "devs have to fix it"
